Rework how GP Backups are accessed

- Now actually from the relevant GP difficulty's Cupgrid, instead of the top-level Play choice
    - Permits a much cleaner M_StartCup, combining two of the previously four copypasted, slightly modified level startup regions (which could be further combined for sanity's sake, but would take a LITTLE more work right now than I have in me)
- Shows a funny exclamation mark from Sonic Rush on the relevant cup on the grid
- Selected by default when loading the menu, if appropriate
