[Feature Request] support hash stability test in lit

[python3kgae]

Is your feature request related to a problem? Please describe. Hash stability test only works in taef and it blocks move taef FileCheck test to lit FileCheck test

Describe the solution you'd like Add a new lit format for hash stability test.

Describe alternatives you've considered Add extra RUN line for all the test shaders. Huge change. Add lit FileCheck folder to the taef hash stability test. It would be nice to not add more taef tests.

Additional context We have lit FileCheck test and taef FileCheck test now. Moving taef FileCheck test to lit FileCheck test folder will reduce the coverage of taef hash stability test.
