Masayuki Nakano 2fde14a338 Bug 1623918 - part 2: Mark nsINode::GetSelectionRootContent() and its root callers as MOZ_CAN_RUN_SCRIPT as far as possible r=smaug
This patch tries to mark root callers of `nsINode::GetSelectionRootContent()`
which calls `nsINode::GetAnonymousRootElementOfTextEditor()` as far as possible
(and reasonable).

It's used by `ContentEventHandler` so that a lot of methods of
`EventStateManager`, `ContentEventHandler`, `IMEContentObserver` which are main
users of it are also marked as `MOZ_CAN_RUN_SCRIPT`.  I think that this is
reasonable.

On the other hand, it might not be reasonable to mark `IMEStateManager` methods
as `MOZ_CAN_RUN_SCRIPT` for initializing `IMEContentObserver` because
`IMEStateManager` may be able to initialize `IMEContentObserver` asynchronously
and its root callers are in XUL layout code.  Therefore, this patch uses
`MOZ_CAN_RUN_SCRIPT_BOUNDARY` for `IMEStateManager` at least for now.
