[libffi] Add pkgconfig file (#12126)

* [libffi] Add pkgconfig file

- Configure and add the libffi.pc file.
- Furthermore, enable the check for same 32/64bit-ness in
  libffiConfigVersion.cmake again, which had caused issues in the past
  with newer versions of glib using meson build, e.g. when building for
  x86-windows target on an x64-windows host.
  Now, libffi is found by current glib (e.g. 2.64.3) during
  meson build using the libffi pkgconfig file.

* Check VCPKG_BUILD_TYPE to handle release/debug
