Gralloc: Use adreno APIs for buffer size calculations

1) Add support to use adreno APIs for non video layers'
buffer size calculations.
2) Add graphics metadata field to MetaData_t structure.
3) Add bindings for newly introduced formats in
GetGpuPixelFormat.
4) Add support to retrieve the graphics metadata in
Perform API.
5) Modify BUFFER_TYPE determination logic
