[CMake] NFC. Add support for testing the compiler without testing the linker
Summary:
One of the big limitations we have in the compiler-rt build system today is that we cannot bootstrap building the builtins because you need a fully functional toolchain to pass CMake's tests.
This change adds support for compile only tests.
It is NFC because nothing is using the compile-only tests yet.
I believe this is the last separable part of D16653.
