Purpose:

Adds support for assembling matrices with >2 active fields that use different bases. This is useful for assembling mixed problems, Lagrange multipliers, etc. without the need for PCFieldSplit. FieldSplit may still be better for a lot of problems, but this is useful for many applications.

LLM/GenAI Disclosure:

None

Most of the codecov is complete nonsense, but it's correct that I'm not testing H-Div/Curl bases.
