[pdm-devel] [RFC pwt] combobox: add .schema() to builder

[Hannes Laimer]

... guarded by the `proxmox-schema` feature.

Very much RFC! Is there a reason to not have this on most elements? This
patch is exemplary, we just pull enum items and default value out of the
schema for the comobox. We could do the same for descriptions or regex
formats.
