Support extruder variants on every printer (#15964)

Browse Source 
# Description

Extruder variants (Standard, High Flow, extra high flow) now work on any
printer. Any vendor profile can declare them, and a multi-variant
filament picks up the right variant on every printer. In the sidebar,
users can switch the printer variant and set the nozzle volume type of
each extruder on multi-extruder printers. This also fixes a later
filament printing at the first filament's temperature on a P1S or X1C
with a High Flow nozzle. The profile checks now reject variant arrays of
the wrong size and outdated variant strings. Every shipped vendor
profile passes them, and the orca-profiles skill documents the rules.

Slicing output changes only where the wrong variant was used before.
