stagefright: misc preliminary fixes for HEIF support
- Support 32bit RGB in ColorConverter.
- Allow dst crop to be not the entire dst frame buffer.
- Also has a minor fix in CallbackDatasource to use left over
cache first before reading from source. This helps to reduce
backward reads to the source.
