Bastian Kersting 95bdb34494 Remove the no_sanitize attribute in favor of sanitize
This removes the #[no_sanitize] attribute, which was behind an unstable
feature named no_sanitize. Instead, we introduce the sanitize attribute
which is more powerful and allows to be extended in the future (instead
of just focusing on turning sanitizers off).

This also makes sanitize(kernel_address = ..) attribute work with
-Zsanitize=address

To do it the same as how clang disables address sanitizer, we now
disable ASAN on sanitize(kernel_address = "off") and KASAN on
sanitize(address = "off").

The same was added to clang in https://reviews.llvm.org/D44981.
