Return caret bounds in local coordinates from GetCaretBoundsInWidget

Return caret bounds in local coordinates from GetCaretBoundsInWidget

This is another regression caused by r197858.
There remains another call site of TextInputClient::GetCaretBounds,
which now returns the caret rect as screen coordinate as
documented in the header.

BUG=239737
TEST=Manually done on Windows 7 with built-in Chinese IME.
