Add op= assignments

For #1144

LGTM, but probably best to let one of the co-chairs do final approval and merging, rather than merging with only my approval.

The biggest question to me is what to do with booleans. And we should be careful to specify which operators apply here, not all binary operators are usable.

@vlstill Are there any remaining concerns you have that have not been addressed? If so, please explain what they are, as the comments that I see appear to be addressed.

[vlstill]

I would probably just add that this is allowed for integral types (bit<N>, int<N>, int).

Main concerns addressed.

@jonathan-dilorenzo Discussed at 2025-Mar-10 LDWG meeting, and vlstill approved during the meeting. If you wish to do a final approval pass before merging, please do so, but we believe this is ready to merge into the spec. FYI, the implementation of this was merged into p4c recently.

@ChrisDodd, can I ask you to add a bullet point summarizing the change to this section before I merge?
