Fix duplicate G29 preparation time (#15274)

Browse Source 
The time estimate added 260 s for every G29 on non-Bambu printers. Prusa MK4, MK4S and CORE One start G-code splits bed leveling across six G29 commands, so those printers showed about 26 extra minutes. The 260 s is now added once per G-code processing run. Bambu printers still only count a G29 inside an M622 J1 block, and their estimates are unchanged.

Fixes #15088
