[vr] Fix AHardwareBuffer GpuMemoryBuffer lifecycle
Creating an AHardwareBuffer-backed SharedMemoryHandle from a file descriptor
takes ownership and needs to auto-close that FD when requested, specifically
when constructed from IPC.
Also fix a reference leak when the received AHardwareBuffer is used to
create an EGLImage since that also increments the refcount.
