TextComposition queries selection start offset a lot of times. Therefore, for reducing the runtime cost, it should use IMEContentObserver if it's available or ContentEventHandler, otherwise.

When composition string hasn't been non-empty, insertion point of the composition string can be changed by a DOM event handler. E.g., compositionstart, first compositionupdate and first text. Therefore, TextComposition should update the composition start offset cache after every event dispatch.

It's enough to store target clause offset from start of the composition and better to modify mCompositionStartOffset because when even if mCompositionStartOffset is changed, we don't need to modify the target clause offset.
This patch renames mCompositionTargetOffset to mTargetClauseOffsetInComposition.

For sending NOTIFY_IME_OF_COMPOSITION_EVENT_HANDLED after the other change notifications which was caused by the user input, we need to use IMEContentObserver::IMENotificationSender because it sends the notifications when it's safe to do it.
This patch makes TextComposition use IMEContentObserver to send the notification. However, if there is no active IMEContentObserver, e.g., composition events are fired on unfocused window, TextComposition sends it by itself (same as current implementation).
If IMEContentObserver stops observing when it has pending NOTIFY_IME_OF_COMPOSITION_EVENT_HANDLED, it cannot send the notification (i.e., it is discarded completely in such case). However, in such case, IMEContentObserver sends NOTIFY_IME_OF_BLUR. So, anyway, native IME handler should treat the blur notification as it including NOTIFY_IME_OF_COMPOSITION_EVENT_HANDLED.
On the other hand, we're buggy if composition events are fired in non-active window. Even in such case, IMEContentObserver should be created for active editor in each document and it notifies IME of the changes. But this is out of the scope of this bug.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.
