android: mm: generic: use GRALLOC_HARDWARE_MODULE_ID
PlatformFrameBufferAllocator is an abstraction over gralloc.
Right now hardwareModule_ points towards a CAMERA_HARDWARE_MODULE_ID.
When gralloc_open() is called we observe:
libcamera: DEBUG HAL camera3_hal.cpp:75 Open camera gpu0
libcamera: ERROR Camera camera.cpp:524 Camera in Configured state trying acquire() requiring state Available
01-23 14:14:04.742 370 416 E libcamera: FATAL HAL generic_frame_buffer_allocator.cpp:105 gralloc_open() failed: -87
Which is wrong, gralloc_open() is attempting to re-open the camera HAL,
instead of the gralloc HAL.
Point to a GRALLOC_HARDWARE_MODULE_ID instead so that we can request
buffers from gralloc in android.
Note: this adds new dependencies on android's libhardware [1] and on libdl.
