  lang/dotnet: fix MidnightBSD native build detection gates

The .NET source build's runtime repo could not build on MidnightBSD: the
VMR vendors a per-repo copy of the native build scripts that only know
FreeBSD, and the LLVM toolchain the port depends on was not discovered.
These changes clear every build-blocking gate through the start of the
CoreCLR native compile (hostfxr/hostpolicy and the managed libraries
build successfully).

post-patch:
- Apply the MidnightBSD handling that the top-level patches add to EVERY
  vendored eng/common/native/init-os-and-arch.sh (OSName midnightbsd ->
  freebsd) and init-distro-rid.sh (freebsd-version -> midnightbsd-version)
  copy. Without this, runtime aborts with
  "Unsupported OS midnightbsd detected!" and cannot read the OS version
  (/bin/freebsd-version does not exist; /bin/midnightbsd-version does).
- Normalize CLR_CMAKE_HOST_OS midnightbsd -> freebsd in the vendored
  configureplatform.cmake copies. CMAKE_SYSTEM_NAME is "MidnightBSD"
  (uname -s), so host arch detection was skipped and cmake died with
  "'amd64' is an unsupported architecture". clang defines __FreeBSD__, so
  the C/C++ sources build unchanged once the OS is recognized.

DOTNET_ENV:
- Set CLR_CC/CLR_CXX to ${LLVM_PREFIX}/bin/clang[++] so the runtime's
  compiler search does not pick up the broken /usr/local/bin/clangNN ->
  bugpointNN symlinks (clangNN -dumpversion runs bugpoint and fails).
- Prepend ${LLVM_PREFIX}/bin to PATH so configuretools.cmake finds
  llvm-ar/nm/ranlib/strings/link/objdump/readelf/objcopy and lld; the
  versioned copies in ${LOCALBASE}/bin are broken bugpoint symlinks.

Note: a full end-to-end build was not completed locally. The parallel
CoreCLR compile at -maxcpucount:${MAKE_JOBS_NUMBER} (16 on the test box)
exhausts memory on a 32 GB machine; capping job count is a likely
follow-up. The fixes here are validated up to and during the native
compile.
