Trigger windowinfo updates when alpha changes

Input and TrustedPresentationListener logic relies on layer alpha. This change ensures
that SurfaceFlinger sends the updated window info when only the alpha changes.

Fixes: 325254898
Test: presubmit
Flag: EXEMPT bugfix
Change-Id: I6b9a5b2874add278245cb682c5362c18403c70b0
