Add rb_gc_mark_and_move and implement on iseq

This commit adds rb_gc_mark_and_move which takes a pointer to an object
and marks it during marking phase and updates references during compaction.
This allows for marking and reference updating to be combined into a
single function, which reduces code duplication and prevents bugs if
marking and reference updating goes out of sync.

This commit also implements rb_gc_mark_and_move on iseq as an example.
