Remove libc from rust_get_test_int uses

`rust_test_helpers.c` has a few unfortunate signatures which have made some of our UI tests _technically_ need the `libc` crate. This is my attempt to evict the need of `libc` for `rust_get_test_int`.

I've deleted `tests/ui/abi/foreign/foreign-no-abi.rs` because the test was originally written to check that `native mod` will compile without an ABI specifier. `native mod` was removed years before 1.0 and the test hasn't checked for anything for a long time.

Clean up users of rust_dbg_call

`rust_dbg_call` is a C test helper that until this PR was declared in C with `void*` arguments and used in Rust _mostly_ with `libc::uintptr_t` arguments. Nearly every user just wants to pass integers around, so I've changed all users to `uint64_t` or `u64`.

The single test that actually used the pointer-ness of the argument is a test for ensuring that Rust can make extern calls outside of tasks. Rust hasn't had tasks for quite a few years now, so I'm deleting that test under the same logic as the test deleted in rust-lang#124073
