This uses a bitfield for flags in FindBoundary, the idea is that it
will give some regression coverage if/when we move the native API
to do the same.

Otherwise, we crash when inspecting RemoteAccessible objects in Dev Tools if the cache is disabled or hasn't been received yet.

Most importantly, this means OffsetAtPoint is now supported for cached RemoteAccessible on Windows.
I also included a drive-by fix to make ATK use the unified CharacterCount method instead of the old unnecessary conditional local/remote paths.

This required changing the RemoteAccessible implementations to return Relation instead of an array of RemoteAccessible.
Platform implementations have been updated to use the unified method where appropriate.

Previously, Relation::Next returned a LocalAccessible.
Now, it returns an Accessible so that it can support RemoteAccessible as well.
Relation::LocalNext has been added as a convenience to return a LocalAccessible when the caller is certain that only LocalAccessible is relevant.
Callers have either been updated to use LocalNext or to handle an Accessible returned from Next.
ia2AccessibleRelation now holds an array of MsaaAccessible, as we need to hold references and we can't hold references to RemoteAccessible.

1. Move AccessKey to base Accessible.
2. Retrieve AccessKey from the cache for RemoteAccessible.
3. Update XPCOM and platform specific code accordingly.

KeyboardShortcut is only supported for XUL menu items.
XUL menu items can never be remote, so there's no point in querying this via IPDL.

We'll probably want to do something more accurate in the future with a
custom clang static analysis pass which validates that XPIDL interfaces
have the expected vtable and struct layout, however doing so would be
more involved than the string matching done in this patch.
In addition to checking for extra virtual methods, we'll likely also
want to check for data members on interfaces, and reject them unless the
class is marked as `[builtinclass]` in addition to some other attribute
which we'll need to add to prevent them from being implemented in Rust
(as c++ data members will not be reflected by the rust macro).
There were 2 instances of a comment which contained the word 'virtual'
within a CDATA block. These comments were moved out of the CDATA block
to avoid triggering the error.

Our hit testing tests need this.
This adds a base Accessible::BoundsInCSSPixels implementation which relies on BoundsInAppUnits.
BoundsInAppUnits was also moved to Accessible, but it is implemented differently for local and remote, so the base method is abstract.
I also did a drive-by removal of a pointless conditional in xpcAccessible::GetBounds.

We implement setting of the caret using HyperText rather than TextLeafPoint because caret stuff, including events, still uses HyperText internally for now.
This moves the async IPDL method already used on non-Windows into the base classes so Windows can use it.
We keep the COM implementation for Windows RemoteAccessible without the cache.
SetCaretOffset was moved into HyperTextAccessibleBase and platform methods were updated accordingly.
Finally, I did some drive-by cleanup (no user impact) and changed GetCaretOffset in ATK and XPCOM to use HyperTextAccessibleBase.
GetCaretOffset was moved to the base some time ago, but ATK and XPCOM weren't updated at the time.

The BrowsingContext already has this information, so we use that instead of redundantly caching it in RemoteAccessible.
This implementation works even when the a11y cache is disabled, so stop using the sync IPDL URL method.
We can't entirely unify the URL method because we don't have a base class for local/remote documents.
However, a method was added in nsAccUtils to unify this as much as possible.

Aside from adding ScrollTo to the Windows PDocAccessible IPDL, This mostly just moves methods into base classes and adapts platform code to use the unified Accessible::ScrollTo.

This doesn't work for non-cached RemoteAccessibles, but this wasn't previously implemented anyway.
With this patch (and all earlier patches in the stack) applied, all the tests in accessible/tests/mochitest pass with the cache enabled, thus testing CachedTableAccessible.

These are needed to support RemoteAccessible tables.
Stuff specific to LocalAccessible is still in TableAccessible and TableCellAccessible, which now inherit from the new Base classes.
Covariant return types have been used to minimise changes in LocalAccessible callers.

Even though we'd ideally be using TextLeafRange for new things, TextRange is still needed by our selection events (which still use HyperText offsets) and IA2/ATK clients which depend on HyperText offsets.
Thus, we need TextRange to support RemoteAccessible.
Although the start and end containers are HyperTextAccessibles, I chose to store Accessible rather than HyperTextAccessibleBase because HyperTextAccessibleBase doesn't inherit from Accessible and having an Accessible is easier.
XPCOM needs to hold a reference to any state objects.
Because we can't hold a reference to an Accessible (due to RemoteAccessible), xpcAccessibleTextRange holds references to xpcAccessibleHyperText instead.

This class needs to be updated to support base Accessible and it doesn't make sense to port methods that can never be used.
Also, any new functionality (e.g. needed for the UIA text pattern) should now be implemented using TextLeafPoint/Range, not TextRange.

Similar to StartOffset:
1. There was a Windows non-cached RemoteAccessible implementation, but it was never actually called, so I removed it.
2. The sync IPDL RemoteAccessible implementation previously provided a boolean indicating success.
I removed this because the LocalAccessible implementation doesn't have this and it doesn't seem like remote is special in this respect.

This also unifies the code path for TextAtOffset in ATK, rather than having different local and remote code paths.
This isn't strictly related to this patch series, but this change was missed before, so I took the opportunity to deal with it here.
