Fix problems after LLVM configuration PRs

Follow-up to PRs #20396 and #20385 to address issues raised by nightly testing.

  • build failures in cron-xc-wb-host-prgenv-cray-failure and
    xc-wb.prgenv-cray configurations: don't default to
    CHPL_LLVM_SUPPORT=system if all the LLVM dependencies are not
    installed. These configurations have just llvm-config but not the
    required headers.
  • networking-packages failure with curl tests: update
    common-quickstart.bash to set CHPL_LLVM=none. The quickstart setup
    script can provide CHPL_LLVM=none or CHPL_LLVM=system but since we
    test CHPL_LLVM=system in most configurations, in the quickstart
    testing configuration, we want to test CHPL_LLVM=none. At the moment,
    the curl tests do not all work with the LLVM backend.
  • darwin-m1 or other Mac OS testing failure with chpl-env-gen: fixed a
    sed portability issue between linux and Mac OS X.

  • On Ubuntu, if llvm-14 is installed but not llvm-14-dev

    • default is CHPL_LLVM=unset and CHPL_LLVM_SUPPORT=bundled
    • setting CHPL_LLVM=system produces an error from printchplenv about a
      missing header

  • On Ubuntu, if we have the needed LLVM dependencies

    • default is CHPL_LLVM=system and CHPL_LLVM_SUPPORT=system

  • make functions on XC with PrgEnv-cray and GCC as the host
    compiler

  • make functions on XC with PrgEnv-cray and cray-prgenv-cray as the
    host compiler

  • full local testing
