Allow changing infill combination layer height

Is your feature request related to a problem?

Currently infill combination height seems to be tied to nozzle width, e.g. always 0.4mm when using a 0.4mm nozzle. This makes some 3d infills unstable especially at low infill percentage. I want to combine infill every 2 layers when printing at 0.1mm layer height.

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

Add a custom config option that changes how many layers got combined/combined infill layer height.

Or just implement #2735 which proposes to make infill combination layer height limited by max layer height.

I don't have examples of worsening infills right now but this post illustrates what I meant:

Basically not enough layer adhesion between infill causing gyroid to form this grid-like pattern.

I cannot use infill combination in my prints because of this. I have max layer height set to 0.2mm on my 0.4mm nozzle and infill combination still wants to print 0.4mm high infills.

same as #2175

I'm really hoping for this!
