It allows us to share the same event name when writing test code like the following:
```
const action = "previoustrack";
mediaSession.setActionHandler(action, () => { ... });
specialPower.generateMediaControlKeyTestEvent(action);

Now that we have UTF8String in the WebIDL, we can remove quite a few of the
conversions. Do that, and lift the remaining string conversions up as needed.
Also deindent Servo_ComputeColor while touching it.
Most of the remaining copies are because either bug 1606994, or because they're
WebIDL attributes that we still need to serialize back as UTF-16 (bug 1606995).

We handle media control key events differently from normal key events, and at this point we haven't finished the implementation of capturing media control key events on each platform. Therefore, create a method to generate platform-independent events in order to help testing.

In order to be able to reasonably debug error results from things like
JSWindowActor.sendQuery, we need to be able to clone errors across process
boundaries, so that they can be propagated to the caller that initiated a
query. The standard for the structured clone algorithm does not allow cloning
errors directly, so this patch instead adds a chrome-only wrapper object which
supports structured clone writing, and on reading, automatically decodes to
the error object it wraps. Callers who wish to clone an Error or Exception
object simply need to wrap it in a ClonedErrorHolder before sending.

This helps retrieving the NodeId for any JS Object you pass in.
This allows identifying a particular object when using HeapSnapshot API.
`HeapSnapshot.computeDominatorTree()` returns a tree of object,
but there is no way to identify a given JS object in it.
Getting the node id of a given JS object helps you browse this tree
from a given object you know is leaking.

The `setCompositionRecording` API on nsIDOMWindowUtils has been broken up into
two new APIs:
* `startCompositionRecording()`, which starts the composition recorder; and
* `stopCompositionRecording(bool writeToDisk)` which stops the composition
recorder and either returns a Promise that resolves to the collected frames
or returns a Promise that resolves when the frames have been written to disk.
The collected frames are serialized over IPC as part of a Shmem as to not
approach the IPC data transfer limit.

Dictionaries that we never initialize with JS values don't need a full-featured
Init() method. Instead, we output a cut-down Init() method that doesn't even
take a JSContext and Value as argument, and skips as much work as it can. It
uses constant-false for "is the value present?", but also, to avoid compilation
errors due to use of `cx` and `val` in now-dead conversion code, it tells the
native-to-JS conversion machinery that the value is always missing, which lets
it skip most of the the work it would normally try to do and just output
initialization to the default value. We only need to do this for members that
have default values; the others either remain no-passed or are required members
with no default-initialization behavior.
This saves about 330KB of codesize on Linux64 without PGO and 285KB with PGO.

This saves about 270KB of codesize on Linux64 without LTO, or 20KB with LTO.
The basic idea is that we can flag dictionaries that need to-JS conversion
(hence ToObjectInternal) based on various IDL uses (return value in normal
interface, argument in callback, etc) and then annotate the ones that are
converted to JS manually in C++ code.
The mozwebidlcodegen changes are needed because non-local changes (e.g. whether
a dictionary is used as a return value somewhere) can now affect the code
generation for a dictionary and hence whether the relevant binding file should
be regenerated. Since these changes can happen in any .webidl file, we need to
check for them. We can't track this via the dependency set on the dictionary
itself, because that would not notice new uses being added.

The changes to the IDL files were done by running this in dom/webidl:
perl -pi -e 'BEGIN { $/ = undef; } s/\[HTMLConstructor,\n Exposed=Window\]\ninterface ([A-Za-z]+) : HTMLElement \{/[Exposed=Window]\ninterface \1 : HTMLElement {\n [HTMLConstructor] constructor();\n/g' *.webidl
