Ironing support interfaces

[Noisyfox]

This allows perfect smooth supported surfaces especially when using multi-material support.

TODOs:

• Add options
• Fix some overlappings/unnecessary ironings (ie, make sure only the top support interfaces are ironed)

[Noisyfox]

Currently both normal ironing & support ironing share the same iron speed (because they use the same extrusion role). Not sure if worth adding a separate speed config.

Though maybe I should also move the iron speed settings to speed tab too.

Not sure if worth adding a separate speed config.

If the support interface would use different filament and with possible toolchangers different nozzle sizes (like is experimental in Prusa XL with PrusaSlicer) then i think it should be separate.

I mean a separate "support ironing speed" than the existing "ironing speed".

Maybe not. But how about add monotonic support interface pattern?

Maybe in a separate PR

Very cool - waiting to read when this gets merged in

Guys, if you're going to be doing this, you REALLY need to implement role-based ironing.

#6979

This provides a quantum leap forward in quality over regular ironing.
