  [Flang] Add OpenMP Conversion patterns

This patch adds the OpenMP conversion patterns to the FIR to LLVM
dialect lowering pass in Codegen. Appropriate legalization
conditions are also added. This ensures that a mix of FIR and OpenMP
dialects can be lowered to LLVM and OpenMP  dialects. Also adds two
tests.

This is part of the upstreaming effort from the fir-dev branch in [1].
