Extract Flang's runtime library to use the LLVM_ENABLE_RUNTIME mechanism. It will only become active when `LLVM_ENABLE_RUNTIMES=flang-rt` is used, which also changes the `FLANG_INCLUDE_RUNTIME` to `OFF` so the old runtime build rules do not conflict. This also means that unless `LLVM_ENABLE_RUNTIMES=flang-rt` is passed, nothing changes with the current build process. Motivation: * Consistency with LLVM's other runtime libraries (compiler-rt, libc, libcxx, openmp offload, ...) * Allows compiling the runtime for multiple targets at once using the LLVM_RUNTIME_TARGETS configuration options * Installs the runtime into the compiler's per-target resource directory so it can be automatically found even when cross-compiling Also see RFC discussion at https://discourse.llvm.org/t/rfc-use-llvm-enable-runtimes-for-flangs-runtime/80826
