Use asynchronous lock/unlock API

The gralloc API now provides a way for using lock/unlock with the Android
explicit synchronisation concept. This changes updates the GraphicBuffer class
to also expose this functionality, and updates the Surface class to make use of
in line with the dequeueBuffer/queueBuffer mechanism.

This new behaviour is dependent on GRALLOC_MODULE_API_VERSION_0_3. If the local
gralloc module does not support this then the existing synchronous lock/unlock
mechanism will be used.
