gralloc : Allow support for both Widevine level-1 and level-3

Browse Source 
MM HEAP will be used only for Widevine Level-1 secure playback.
Since Video component assures of using MM HEAP flags only for
WV Level-1 and Level-3 will not be marked with MM HEAP it is
possible to allow supporting both of these protection levels
co existing in a device.
