Implements maxColorAttachmentBytesPerSample 

- Adds the limit
- Adds relevant format-specific data into format table
- Adds deprecation validations regarding the limit
- Adds deprecation validation unit tests and helpful utils
- Moves deprecated api tests from end2end to unittests, allowing tests
  to be cross-files for ease after deprecation.
- Updates some validation messages to include helpful contexts.
