Follow up from D92955 and D83636. This patch makes the base cpp files OMP.cpp and ACC.cpp normal files and they now include the XXX.inc file generated by tablegen. This reduces the number of file generated by the DirectiveEmitter backend and makes it closer to the proposal in D83636. Reviewed By: Meinersbur Differential Revision: https://reviews.llvm.org/D93560
