EditorBase::CreateTxnForComposition() just hides what it does. For its caller,
creating a factory method, CompositionTransaction::Create(), is clearer what
it does.
Additionally, capsuling the creation in CompositionTransaction class can make
the text node information in TextComposition updated automatically. So, now,
it might be better to update them in DoTransaction() because there is a lag
between creating the transaction and calling DoTransaction(). However, this
patch doesn't want to change any existing behavior. So, this doesn't fix this
issue.

EditorBase stores a text node, offset in it and length in it of composition
string directly. However, this wastes memory space if user never uses IME
or user only sometimes uses IME. Additionally, storing all data in
TextComposition is better than current design when other classes like
CompositionTransaction wants some information of both EditorBase and
TextComposition.
This patch moves those 3 members from EditorBase to TextComposition.

According to the log in crash reports, eCompositionCommitRequestHandled is
sent to ContentCacheInParent twice or more for a composition. This causes
breaking mPendingCompositionCount and mPendingEventsNeedingAck management.
Currently, nsIWidget::NotifyIME() should be called only by
TextComposition::RequestToCommit(). Therefore, the method should manage if
it should request it actually. If the composition has already received
eCompositionCommit(AsIs) event, it shouldn't request it because parent process
may have already stated new composition and it shouldn't be broken by request
for old composition.

IME should receive notifications and requests only from proper process. E.g., IME shouldn't commit composition by a request which came from previous focused process.
This patch makes that IMEStateManager::NotifyIME() takes pointer to TabParent optionally. If the request or notification came from remote process, it should be non-nullptr. Then, this makes it ignore notifications and requests from unexpected process.
Note that this patch also touches some gfx headers because they use |ipc::| but compiler is confused at the ambiguousness between |mozilla::ipc::| and |mozilla::dom::ipc::|.
Finally, this patch changes the NS_ASSERTION in IMEHandler::OnDestroyWindow() to MOZ_ASSERT because the orange caused by the NS_ASSERTION was not realized since there was already an intermittent orange bug caused by different NS_ASSERTION.

TextComposition in the main process is destroyed when the main process sends eCompositionCommit(AsIs) to focused remote process. Therefore, ContentCacheInParent::mCompositionPendingCount is never 2 or more now.
It may cause ContentCacheInParent::Assign() setting older composition's start offset to current composition's start offset in the main process.
For making uplift the following patch easier, the wrong patch should be backed out first.

ContentCacheInParent::mPendingCompositionCount is now managed with composition events which TabParent received. However, TextComposition doesn't dispatch composition events after coming request to commit active composition. Therefore, composition is committed forcibly in a remote process over 255 times, the main process crashes.
It's the safest way to use TextComposition to manage ContentCacheInParent::mPendingCompositionCount.

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.
