anv/android: add GetAndroidHardwareBufferPropertiesANDROID
Use the anv_format address in formats table as implementation-defined
external format identifier for now. When adding YUV format support this
might need to change.
v2: code cleanup (Jason)
v3: set anv_format address as identifier
v4: setup suggestedYcbcrModel and suggested[X|Y]ChromaOffset
as expected for HAL_PIXEL_FORMAT_NV12_Y_TILED_INTEL
v5: set linear tiling for GPU_DATA_BUFFER usage, add comment
about multi-bo support to clarify current implementation (Lionel)
