validation: clean up function attributes validation and unit-tests 

- clean up function decorations unit tests
- clean up interpolate and invariant validation and unittest
- add separate unit-tests for each shader stage input and output
- add [[builtin(position)]] tests
- add validation and test for:
structures with 'location' decorated members cannot be used as compute shaders input
