API validation test for debug groups and markers

Test Coverage:
  - For each encoder type (GPUCommandEncoder, GPUComputeEncoder, GPURenderPassEncoder,
  GPURenderBundleEncoder):
    - Test that all pushDebugGroup must have a corresponding popDebugGroup
      - Push and pop counts of 0, 1, and 2 will be used.
      - An error must be generated for non matching counts.
    - Test calling pushDebugGroup with empty and non-empty strings.
    - Test inserting a debug marker with empty and non-empty strings.
    - Test strings with \0 in them.
    - Test non-ASCII strings.
