The linker is implemented using a Babel transform such that Babel needs to parse and walk a source file to find the declarations that need to be compiled. If it can be determined that a source file is known not to contain any declarations the parsing and walking can be skipped as a performance improvement. This commit adds an exposed function for tools that integrate the linker to use to allow short-circuiting of the linker transform. PR Close #40137
