Add isUidActiveOrForeground() for camera/audio to use.
When start/resume activity, WindowManagerService start/resume the
activity, then post a runnable to DiaplayThread and
ActivityManagerService to update UidRecord's
proc state, because the thread switch, the latency before proc
state update is undetermined.
When CameraService calls ActivityManagerService.isUidActive(), the proc
state may not have been updated and camera access is denied.
isUidActiveOrForeground() will check isUidActive() first, if false,
check isUidForeground() which is actually to check with WindowManagerService if
the uid is foreground, which is equivalent to ActivityManagerService's uid
active, just updated earlier.
