"World War Doh" binds uniform buffers via glBindBufferBase() calls
before any frames have rendered and then uses those bound buffers for
all subsequent frames. ANGLE's frame capture was failing to perform
these calls during the mid-execution capture setup phase, leading to
the replay generating VVL errors:
  VUID-vkCmdDispatch-None-02699
  Descriptor in binding #0 index 0 is being used in draw but has never
  been updated via vkUpdateDescriptorSets() or a similar call.

This CL adds those calls to the MEC setup phase, allowing the replay to
execute without any errors.
