LP64 fixes for camera_metadata.

camera_metadata packets are transferred across process
boundaries with Parcel::readBlob / Parcel::writeBlob calls
so we should make sure they have a consistent layout across
32 and 64 bit processes. In this change :

- Replace size_t members with uint32_t members.
- Remove the "void*" user pointer which is no longer required
