Reland "Fix an edge case bug in Windows TSF1 implementation."

Reason for reland:
  1. The original change cause regression in Omnibox with Korean
autocomplete feature. The root cause is that during Korean IME, we do
not reset |selection_| member during |ResetCacheAfterEditSession| if
current selection is interim char selection.
  2. Windows Voice Access tool may change selection without starting
new composition in "Select that" command. We should update text input
client with new selection in this scanrio.

Original change's description:
> Fix an edge case bug in Windows TSF1 implementation.
>
> There is a bug in TSF1 impl where IME such as voice typing can select
> text before composition start when user says "select that" command. In
> this case, we need to select text that is before composition start.
