gralloc: Use only 'data' member in GraphicsMetadata

- In gralloc3, first member 'size' in GraphicsMetadata struct was
  never unused in call to GetGraphicsMetadata. Get() call always
  returned 'data' member in GraphicsMetadata structure.

- Gralloc4 implementation introduced new encode/decode functions for
  GraphicsMetadata which are simultaneously used during set/get
  calls to encode/decode  metadata for caller and during storing/
  retrieving it from Metadata_t struct. Get() call returned
  GraphicsMetadata struct pointing to its first member 'size'
  instead of second member 'data'.

- Implement function to encode/decode GraphicsMetadataRaw to translate
  the metadata before calling mapper set/get.

- Update encodeGraphicsMetadata/decodeGraphicsMetadata functions to
  store/retrieve only 'data' member in GraphicsMetadata structure.
