The patch implements the methods as rb_f_notimplement.
To test for compaction users can now use `GC.respond_to?(:compact)`.
The upstream patch relies on the macro `GC_COMPACTION_SUPPORTED`
that is defined when the `__wasi__` is false. The define is defined by
an arch conditional in the specfile, which is not optimal but works in our case.

This also requires regenerating the gc.rbinc and miniprelude.c
since the patch touches gc.rb. This patch is available in
ruby-3.2.0-define-unsupported-gc-compaction-methods_generated-files.patch.
To regenerate the gc.rbinc and miniprelude.c files patch:
