This commit adds a new `TableGenParseFile` entry point for tablegen that parses an input buffer and invokes a callback function with a record keeper (notably without an output buffer). This kind of entry point is very useful for tablegen consuming tools that don't create output, and want invoke tablegen multiple times. The current way that we interact with tablegen is via relative includes to TGParser(not great). Differential Revision: https://reviews.llvm.org/D119899
