bpo-41054: Simplify resource compilation on Windows (GH-21004)


Remove auto-generated resource header. Pass definitions required
by resource files (ORIGINAL_FILENAME and FIELD3) directly to resource
compiler.

Remove unused MS_DLL_ID resource string and related dead code.
(cherry picked from commit 4efc3360c9a83d5891f27ed67b4f0ab7275d2ab4)
