This is exposing the basic functionalities (create, nest, addPass, run) of the PassManager through the C API in the new header: `include/mlir-c/Pass.h`. In order to exercise it in the unit-test, a basic TableGen backend is also provided to generate a simple C wrapper around the pass constructor. It is used to expose the libTransforms passes to the C API. Reviewed By: stellaraccident, ftynse Differential Revision: https://reviews.llvm.org/D90667
