Auto merge of #117525 - GKFX:remove_option_payload_ptr, r=petrochenkov
Remove option_payload_ptr; redundant to offset_of The `option_payload_ptr` intrinsic is no longer required as `offset_of` supports traversing enums (#114208). This PR removes it in order to dogfood offset_of (as suggested at https://github.com/rust-lang/rust/issues/106655#issuecomment-1790907626). However, it will not build until those changes reach beta (which I think is within the next 8 days?) so I've opened it as a draft.
