[flang][driver] Add support for -fopenmp and -fopenacc

Add support for the following options:
* -fopenmp
* -fopenacc

Update OpenMP and OpenACC semantics tests to use the new driver if it is built, otherwise use f18.
OpenMP tests that include `use omp_lib` or run `test_symbols.sh` have not been updated as they require options `-intrinsic-module-directory` and `-funparse-with-symbols` which are currently not implemented in the new driver.
Similarly OpenACC tests that run `test_symbols.sh` have not been updated.

This patch also moves semanticsContext to CompilerInvocation and creates it in CompilerInvocation#setSemanticsOpts so that the semantics context can use Fortran::parser::Options#features.

Summary of changes:
- Move semanticsContext to CompilerInvocation.h
- Update OpenMP and OpenACC semantics tests that do not rely on `-intrinsic-module-directory` and `-funparse-with-symbols` to use %flang
