MSVC builds must use a separate stamp file for copying generated headers.

Commit bad51a4 tried to use a shortcut with just one stamp file
recording the actions of generating the pg_*_d.h headers and copying
them to the src/include/catalog/ directory.  That doesn't work in all
scenarios though, so we must use two stamp files like the Makefiles do.
