Autogen: Improved multi-config include scheme

For multi configuration generators AUTOMOC generates the
moc files that are included in `mocs_compilation.cpp`
in `AUTOGEN_BUILD_DIR/include_$<CONFIG>/`. By doing so each
configuration reads different moc files when compiling
`mocs_compilation.cpp`. Since we do not (need to) rewrite
`mocs_compilation.cpp` on a configuration change anymore,
the files also does not need to be recompiled anymore.
Not having to rewrite and recompile `mocs_compilation.cpp`
on a configuration change anymore was the main objective of
this patch.

In a similar fashion AUTORCC generates a `qrc_BASE_CMAKE.cpp`
file below `AUTOGEN_BUILD_DIR/include_$<CONFIG>/` and
`qrc_BASE.cpp` becomes a mere wrapper that includes this
actuall rcc output file (when using multi configuration
generators).

The template files `Modules/AutoRccInfo.cmake.in` and
`Modules/AutogenInfo.cmake.in` were removed in favor
of writing the info `.cmake` files manually.

Closes #17230
