Remove compiler-rt, profile and sanitizers when using --no-runtimes

The flag removes the compiler-rt runtime from the build, as well as
the profile and sanitizers runtimes, as they are not needed for building
the Rust toolchain and are distributed with the C++ toolchain.

This makes the Rust toolchain builds a bit faster.

One exception is that MacOS always needs compiler-rt in order to link
LLVM binaries, so it's not removed on MacOS.
