frontents/va: Use PIPE_USAGE_STAGING for coded buffer

Coded buffer will only be read on CPU, setting
PIPE_USAGE_STAGING instead of PIPE_USAGE_STREAM
makes the CPU reads much faster.

On 6700XT this reduces the CPU copy by around
3ms to 0.3 ms on average while under high GPU
load - real-time game streaming.
