tests: remove compiler requirement in various unneeded cases

Compiled languages are Meson's bread and butter, but hardly required.
This is convenient, because many test caases specifically, do not care
about testing the compiler interactions.

In such cases, we can skip doing compiler lookups which aren't used, as
they only slow down test setup.
