Description

Workaround for #11362, #9330, and other similar issues that appear from time to time.

In short, Orcanic supports can be generated in the air.

This problem drives me crazy because it makes miniature printing difficult.

This issue exists in BBS and Prusa Slicer as well. It's really hard to fix because the code is too messy and hard to read and understand. Too many hacks, code duplication, a lot of solutions mixed, etc. So, this PR introduces a workaround to enable the base patterns (infill) for Organic supports.

Organic Tree supports were intentionally implemented as hollow, and I don't understand why. Three out of four infills work very well for Organic (according to my tests).

This PR is small and does not introduce any big changes.

Known issues:

Lightning infill is not supported - some code is missing, and it's crashing if I try to enable it.
Double walls are supported only for the hollow type. If the base pattern is not hollow, only one wall will be used.

Both of these issues require significant code changes, which I don't want to make (it's a trap).

Instead, I described them as limitations via tooltips and/or warning messages.

I'd appreciate it if you could share your opinions and thoughts.

Now problematic supports can have at least something under them. It will save so much time and stress for many people.
