GpuArcVideoEncodeAccelerator: Initialize bitstream_buffer id to 0

GpuArcVideoEncodeAccelerator doesn't initialize bitstream buffer id. The random
number bitstream buffer id is passed to VEA::UseOutputBitstreamBuffer() at first
and later will pass some middle number as a result of bit operation. Bitstream
buffer id should be initialized by 0. This also set the inital value of
|input_storage_type_| to kShmem.

Bug: None
Test: Confirm bitstream buffer id is 0 in VEA::UseOutputBitstreamBuffer().
