llvmPackages_{12,13,git}.compiler-rt: remove new runtimes in useLLVM

LLVM 12 added the memory profiling runtime and LLVM 13 the ORC
runtime. Both need a libc in order to build (or at least headers not
present in clang's resource root), so we'll disable them for any sort of
baremetal-ish build. memprof likely doesn't work in a baremetal
situation at all, orc is unknown. Whether both would compile with musl
is to be checked.
