gralloc: expose Gralloc4 get/dump functions

Expose Gralloc4 functions up to GraphicBufferAllocator/Mapper.
By adding the functions to GraphicBufferAllocator/Mapper,
the rest of the system can depend on GraphicBufferAllocator/Mapper
instead of talking directly to IAllocator/IMapper.

Bug: 141632767
Test: Implementation will be tested through
        VtsHalGraphicsMapperV4_0TargetTest
      Framework plumbing will be testing when it is exposed to
        GraphicBuffer
