fix(patch-conflict): wrap HideLiveCaptionDialogForGestureIfNecessary in #if 0

Upstream added a new helper function HideLiveCaptionDialogForGestureIfNecessary
as part of gesture handling refactor. This function accesses live_caption_dialog_
which is an incomplete type since Electron disables the live caption feature
by wrapping its include in #if 0.

Wrapped the new function declaration in header and implementation in #if 0
guards to match existing pattern for disabled live caption functionality.
