[C++20] [Modules] Emit Macro Definition in -module-file-info action

It is helpful to know whih macro definition is emitted in the module
file without openning it directly. And this is not easy to be tested
with the lit test. So this patch add the facility to emit macro
definitions in `-module-file-info` action. And this should be innnocent
for every other cases.
