shader_jit/tests: Test both the shader interpreter and jit (#72)

Browse source 
* shader_jit/tests: Test both the shader interpreter and jit

Uses Catch2's `TEMPLATE_TEST_CASE`-feature to test both the JIT and the
interpreter.

* shader_jit/tests: Use generator-expressions for nested-loop test cases

Tests more permutations of inputs than just the two it had before

* shader/tests: Refactor `shader_jit` tests to just `shader` tests

Since these tests will test both the interpreter and the jit, they are no longer jit-specific tests and are more general shader-tests.

* shaders/tests: Disable Nested-Loop `ShaderInterpreterTest` test

Restoring loop-state on nested loops is bugged on the ShaderInterpreter.

* shader/tests: Fix Nested Loop generator expressions
