v3dv/android: Enable shared presentable image support

Functionality ensures gralloc won't allocate compressed buffer
incompatible with shared presentable image support.

Broadcom does not support compressed buffers and we can just enable the
feature without additional logic. Despite that, we add the logic here
so it can be replaced with the generic code someday.
