cranelift: Register all functions in test file for interpreter

[afonso360]

👋 Hey,

This does a similar refactor to #4667 but for the interpreter. Mostly to ensure that we can keep adding test interpret to any run tests that may come up.

call_indirect tests are not enabled because we don't support them yet.

It also implements bnot for booleans since one of the call tests uses it.

Looks good to me!

This seems to be causing a regression on main, probably due to a stale test run:

thread 'worker #7' panicked at 'Unexpected returned control flow: Trap(User(BadSignature))', cranelift/filetests/src/test_interpret.rs:112:29
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
FAIL filetests/filetests/runtests/call.clif: panicked in worker #7: Unexpected returned control flow: Trap(User(BadSignature))
506 tests
Error: 1 failure

I'll create a revert PR for this momentarily!
