LOG: [flang] Rename `flang` as `flang-to-external-fc`

Our ultimate goal is to rename `flang-new` as `flang`. This is "Step 1"
in which we only rename the bash wrapper script, `flang`, as
`flang-to-external-fc`. The new name more accurately reflects what the
wrapper script does.

With this patch, `flang` becomes a symbolic link pointing to
`flang-to-external-fc`. This allows a smooth transmission for any
buildbots that use this script. Once the buildbots are reconfigured to
use the updated name, CMake rule for the symbolic link will be removed.

  * https://reviews.llvm.org/D125788.
