This avoids the small overhead and potential for bugs from the previous
approach of assuming all `const char*` arguments passed to `nsITimer`
initializers are string literals, by instead requiring the argument to be a
`const nsACString&`. This involves changing all callsites to pass a `""_ns`
string literal down instead of a bare string literal.
It appears that while there were currently no buggy callers which
would've provided a dynamic string, there was at least one piece of code
(nsRepeatService::Start) which did pass down a raw char* which may be
dynamically allocated (all callers pass down `nsLiteralCString` so we're
actually OK here right now, but this was a footgun).

We are making changes to many files. Very huge chunk of the changes are just renaming CSP -> PolicyContainer. Part 1 and part 2 are solely separated as frontend and backend. The unfortunate thing is, I mistakenly placed IDL changes in part 1, and many of those IDL changes affect frontend code too. I'm sorry for this inconvinience and hard to review patch(es).
(FWIW before this rewrite we had [another patch stack](https://phabricator.services.mozilla.com/D247332). It is 25 patches and I believe isn't as comprehensive as this one. It also didn't replace CSP's inheritance but was copied alongside with CSP, but we decided to change our method and make policy conttainer contain CSP and copy it around after some discussion and reviews)

`screenX`, `screenY`, `clientX`, `clientY`, `x`, `y`, `offsetX` and `offsetY`
are now `double`. This patch makes the event classes aware of DOM events.
Currently, Chrome allows fractional values only for pointer events whose type
is not `click`, `auxclick` nor `contextmenu` (this exception is defined by the
Pointer Events spec). Therefore, this patch follows them.
I'm not sure about the untrusted events of non-pointer events, `click`,
`auxclick` and `contextmenu`. Chrome does check whether it's trusted or not
before applying `std::floor` or `std::round` at getter methods (I think that
using `std::round` in `offsetX` and `offsetY` is their bug at least for
untrusted events). This patch follows them for now but has a pref to allow
for all untrusted events.
Finally, for aligning to Chrome, this patch makes `click`, `auxclick` and
`contextmneu` keep using integer coordinates because it's recommended by the
Pointer Events spec.
Note that this changes the logic in `Event::GetPageCoords`. It rounded the
client point and scroll point before adding them. Similarly,
`Event::GetOffsetCoords` too. It rounded the client point before transforming
it. Therefore, in strictly speaking, this changes the behavior of other events
which keep returning integer coordinates. However, I don't see any issues in
our CI. So, for making the code simpler, let's use it and once we got some
regression reports caused by this, let's make them take additional param to
round the points to integer done in the traditional code.

This is all super-hacky (see a lot of the XXXcjones comments).
Simplify it... We never create widgets with a bare native parent but no
nsIWidget parent. Pass nsIWidgets and deal with things correctly.
There were also things that were dealing with stuff that can't happen,
like top level popups, children of PuppetWidgets, or such.
Instead of overriding Create(), let's just teach nsBaseWidget about
non-native (headless/puppet) widgets.
Remove lots of old APIs for the native window stuff that are unused
and/or unimplemented.

Sorry this is not a particularly easy patch to review. But it should be
mostly straight-forward.
I kept Document::Dispatch mostly for convenience, but could be
cleaned-up too / changed by SchedulerGroup::Dispatch. Similarly maybe
that can just be NS_DispatchToMainThread if we add an NS_IsMainThread
check there or something (to preserve shutdown semantics).

Calling `UpdateDefaultPreventedOnContent` separately from

The EditorEventListener for HTMLEditor is registered on document,
which is problematic because it can't receive events when the focus is
switched between elements in the same shadow tree due to shadow dom
encapsulation.
We fix this by moving the EditorEventListener to nsWindowRoot so the
events can always be received.

Because the parent process lacks information about the current shell
size, the child has to send both the current and the new shell size to
the parent. The parent then applies the delta to the window size. This
can produce different results for calls with the same arguments,
whenever a previous call did not have enough time to update the child
with its new size.
The implementation is replaced by applying the delta in the child.

Implementations of nsIEmbeddingSiteWindow and nsIBaseWindow largely
overlap, and where they don't, the nsIEmbeddingSiteWindow implementation
of the otherwise shared interface is primarily stubbed out with the
exception of Get/SetDimensions().
This patch moves a reimplementation of Get/SetDimensions() from
nsIEmbeddingSiteWindow to nsIBaseWindow. The other methods of
nsIEmbeddingSiteWindow remain covered by nsIBaseWindow.
Get/SetDimensions() can be implemented as part of nsIWebBrowserChrome
where nsIBaseWindow is not necessary. This removes the need for
nsIEmbeddingSiteWindow.
Blur() has also been moved to nsIWebBrowserChrome, as only
nsContentTreeOwner has an actual implementation which we in theory also
want to call from BrowserChild/Parent, but the spec suggests to
"selectively or uniformly ignore calls".
GetVisibility() had an implementation in BrowserChild that pretended to
always be visible. Instead of providing an interface for that,
nsDocShell now handles the not implemented case for tree owners.
nsIEmbeddingSiteWindow::GetSiteWindow() used to call through to
nsIBaseWindow::GetParentNativeWindow().
The Get/SetDimensions() implementation has been replaced with a strongly
typed setter, which is now also used directly from nsGlobalWindowOuter
to avoid problems that come with autodetecting unchanged dimensions,
when the current dimensions are outdated (e.g. immediately reverting a
change can be ignored).

Only GeckoMVMContext really needs the flush, to measure scrolled height
afterwards. Do that explicitly.
This shouldn't change behavior, for the most part; there was a preload
test that relied on the flush when changing DPI to start a run really
clean, but other than that this looks green on try.
Should at best be neutral (just code clean-up), or be a performance
improvement.
In a follow-up, we can possibly remove the DelayedResize code from the
view manager, though I need to think how to possibly coalesce the MVM
reflows, so let's not do that yet.
