For OOP iframes, the top level document lives in a different process.
Previously, we incorrectly returned the top level document in the same process.
This was causing JAWS to incorrectly identify OOP iframe documents as separate tab documents.
To fix this, we must send the real top level document down from the parent process and return that when requested in the content process.

This wasn't useful cross-platform.
ATK was the only consumer of this and it now uses ProxyAccessible::ChildAtPoint.
This also means the related aNeedsScreenCoords functionality in PDocAccessible::AccessibleAtPoint is no longer needed and has thus been removed.
Finally, this renames PDocAccessible::AccessibleAtPoint to PDocAccessible::ChildAtPoint for consistency with Accessible::ChildAtPoint now that the functionality is mirrored.

Accessible::ChildAtPoint can return an Accessible in a descendant document.
Thus, we must return the result PDocAccessible via IPC, not just the id.
Previously, we only returned the id, but we'd fail when we tried to look it up if it belonged to a descendant document.

This code (and an upcoming dependent patch) is currently behind a pref which is disabled by default, as there is uncertainty as to how it might impact the Dev Tools A11y Panel.
The A11y Panel is currently a moving target due to ongoing refactor for Fission.
This pref should be removed once that groundwork is complete and the impact has been verified.
This patch also includes fixes to some ProxyAccessible methods which previously crashed when there was no parent, as is the case for top level documents.
Without these fixes, the Dev Tools A11y Panel would crash the parent process.

When window emulation is enabled, each tab document gets its own HWND.
OOP iframes get the same HWND as their tab document and fire events with that HWND.
However, the root accessible for the HWND (the tab document) can't return accessibles for OOP iframes.
Therefore, we must get the root accessible from the main HWND and call accChild on that instead.
We must do this in the parent process, but the tab document accessible is in the content process.
Although OOP a11y clients talk directly to the content process, the clients that need window emulation are in-process.
All in-process client calls get intercepted by AccessibleHandler, so we can deal with this forwarding in AccessibleHandler.

Windows programs run via Wine don't like Unix absolute paths (they look
like command line arguments), so we need to use relative paths.
Mingw already run fxc2 via wine, but for some reason it doesn't care
about the Unix absolute paths. genshaders does need some adjustements to
run properly with the real fxc.
Now, on actual Windows, because the temporary directory where
tempfile.NamedTemporaryFile creates files by default is not necessarily
on the same drive as where the command runs from, a relative path can't
be constructed. So we also force the temporary file to be created in the
current (obj) directory.
There is no similar concern for other files because we only go from
objdir to srcdir, and the build system already doesn't support both
being on a separate drive.
While here, flush stdout when the genshared script writes to it, so that
the messages are printed out immediately rather than randomly, later,
after output from subprocesses.

Which I really didn't feel like digging into.
* I had to restore the order of TrustOverrideUtils.h and related files in nss
because the .inc files depend on TrustOverrideUtils.h being included earlier.
* I had to add a missing include to RollingNumber.h
* Also had to partially restore include order in JsepSessionImpl.cpp to avoid
some -WError issues due to some static inline functions being defined in a

On Windows, if the top level document hasn't received its parent COM proxy yet, sending constructors for child documents will be deferred.
If an OuterDocAccessible for an OOP iframe is created inside a child document before its constructor is sent, we must also defer the call to BrowserBridgeChild::SendSetEmbedderAccessible.
previously, we tried to send the embedder before the document constructor was sent, causing a crash.

This is an alternative to carrying a revert of the offending changeset, since the bug doesn't show hope of a fix anytime soon, or maybe ever. This way we don't have to keep rebasing the patch as we pick up new clangs, and developers don't have to remember to apply the patch when building a local compiler.

For paragraphs, divs, spans, etc., a11y focus on Android goes to text leaf Accessibles, rather than to the HyperTextAccessible container.
This does make sense, as these containers frequently embed other content, so the text needs to be reachable as a separate item.
However, previously, performing text navigation on these text leaf Accessibles returned the HyperTextAccessible parent.
This isn't supported by Talkback, and even if it were, it causes other problems; e.g. a11y focus being lost if the user was focused on a child other than the first child of such a container.
Therefore, if text navigation was performed on a text leaf Accessible, we now return a result within the text leaf Accessible if possible, rather than the HyperTextAccessible.
1. Make AccessibleWrap::GetTextContents support text leaf Accessibles (for both local and remote proxied Accessibles).
This is used when providing text for text traversal events.
2. When navigating text on Android, we use Pivot::Next/PrevText.
However, this will always return a HyperTextAccessible, even when starting on a text leaf.
Therefore, if the result from Pivot::Next/prevText resides entirely within the same text leaf, translate the offsets from the HyperTextAccessible so they're relative to the text leaf and return the text leaf.
3. Pivot::Next/PrevText already supported starting from a text leaf Accessible.
However, they ignored the offsets, which meant that navigating from a text leaf would always navigate to the start/end of the text leaf.
Now, if a text leaf is passed to Pivot::Next/PrevText, the offsets (if specified) are translated to the HyperTextAccessible parent first.
4. Adjust the existing character/word/line tests so they ensure that navigation returns the node that has a11y focus; i.e. the text leaf.

1. When creating a DocAccessibleParent for an embedded document in an OOP iframe, it's possible that the embedder accessible hasn't been set yet.
This can occur if the iframe is initially hidden.
Previously, we incorrectly set the document up as a top level document (e.g. tab document) in this case.
Now, we set up the document as top level in its content process, set up the proxy, etc.
The document will be added to its child document later when the embedder is set.
2. When setting the embedder accessible for an OOP iframe, check if the embedded DocAccessibleParent already exists.
This can happen if an iframe is hidden and then shown or an iframe is reflowed by layout.
If it already exists, add the embedded (child) document to its embedder.
3. Mac's implementation of ProxyCreated requires that AddChildDoc be called *before* ProxyCreated so it can invalidate the native children of the parent.
Because it's possible for an OOP iframe document to be added to its embedder after the document is created, we can't satisfy this requirement for OOP iframe documents.
Therefore, we now allow a null parent in Mac's ProxyCreated and use the reorder event fired later to invalidate the native children.
