[X86] Add missing scheduling class tag for i64 absolute address moves

Expand existing SchedRW to encompass these like it did for the other memory offset movs - added comments to closing braces to keep track of def scopes.

We only tagged it with the itinerary class, so completeness checks were erroneously passed (PR35639).
