gfxstream: make sure we consistently use uint32_t instead of int32_t to read the packet size.

A negative packet size doesn't make sense, and the code currently doesn't try to handle that scenario (ie: all 4 stream decoders do `ptr += packetLen` and as such would move backwards if the length was negative.

Further, on the encoder side, uint32_t is used (e.g.:

Test: compiles, runs
