Ensure surfaces only resize during relayout.

For clients which use an indeterminate measure spec in their
layout params (MATCH_PARENT). We could try and change their window size
due to a stack resize, before the client calls relayout. This isn't
safe as the client never had an opportunity to pause rendering, so it
could be in the middle of producing a frame for the old size to suddenly
find the buffer size change underneath it.
