[flang][driver] Remove Fortain_main static library from linking stages (#75816)
At present, when building static or shared libraries, Flang adds
`-lFortran_main.a` (or `/WHOLEARCHIVE:Fortran.*.lib` pon Windows) to the
link line. This leads to the problem that `_QQmain` and
`_QQEnvironmentDefaults` (as of the time of this PR) are symbols marked
as used, while `main` is being defined. This should not happen and this
PR fixes this by detecting if `-shared` or `-static` is used on the
Flang command line and removing the static `Fortran_main` library.
