Add more tests, refactor array lengths/consteval work
Fix #2922: add unknown length as a condition for a type having unknown. Incorporate reviews: * Extract some of the const evaluation workings into functions * Add fixmes on the hacks * Add tests for impls on specific array lengths (these work!!! 😁) * Add tests for const generics (indeed we don't support it yet)
