Add shader-jit unit-tests (#458)

Browse source 
* Rename `dynapica` TU to `shader`

These unit-tests in particular only actually test
the shader-interpreter and not any of the JITs.

* Conditionally test the shader-jit

In the case that the host supports the shader-jit, the interpreter and the shader-jit will both be tested with the same unit-tests. Allowing for even more coverage.

* Remove weird git submodule
