[flang][tests] Enable some fixed tests, disable some with valid new errors

Many gfortran regression tests that were disabled because they failed
have been fixed in llvm-project/main, and can now be removed from the
DisabledFiles.cmake file.  Some tests that were compiling and running
no longer do so because they contain valid errors that are now detected
by flang at compilation time.
