compiler_types: mark __compiletime_assert failure as __noreturn

`__compiletime_assert` declares a fake `extern` function
which appears (to the compiler) to be called when the test fails.

Therefore, compilers may emit possibly-uninitialized warnings
in some cases, even if it will be an error anyway (for compilers
supporting the `error` attribute, e.g. GCC and Clang >= 14)
or a link failure (for those that do not, e.g. Clang < 14).

Annotating the fake function as `__noreturn` gives them
the information they need to avoid the warning,
e.g. see https://godbolt.org/z/x1v69jjYY.
