### Description
1. move the cache task definition into template
2. In debug mode, the compiler mtime is different in different machine.
So, change the CCACHE_COMPILERCHECK to content.
### Motivation and Context
1. Accelerate the CoreML pipeline.
Test run:
https://dev.azure.com/onnxruntime/onnxruntime/_build/results?buildId=938040&view=logs&j=1ac7588f-a5bd-5ff7-4a8a-a34869d50220
With Cache, the run can be finished in 12 minutes. Without cache, it
takes about 1 hour.
3. Make the cache function easy to use and maintain.
