Eliminate a sync cancelComposition call in WebPageProxy::editorStateChanged
https://bugs.webkit.org/show_bug.cgi?id=130727

Reviewed by Enrica Casucci.

Added a separate CompositionWasCanceled IPC call, with which WebProcess can tell
UIProcess that it should notify an input method of canceled composition. There are
a lot of incorrect edge cases where we don't call it correctly, but this was true
in the old implementation too (for different edge cases).

This change only affects iOS and async NSTextInputClient code path on Mac. I don't
want to change sync NSTextInputClient code path unless absolutely necessary.

Support form controls that may need incremental redraw
https://bugs.webkit.org/show_bug.cgi?id=130736

Reviewed by Beth Dakin.

There are some form controls that change appearance
over time. Expand the ControlStates so that it can
hold a little more information, including a reference
to the native form control. This way the Theme implementation
can repaint the existing native control if necessary. At
least ThemeMac was reusing a single control for painting
all instances before this change.

Since ControlStates is now a class, pass it around by
reference.

The other major change is keeping a timer to trigger a
repaint in RenderBox, which happens if Theme/RenderTheme
update the ControlState to request one.
