And.controlled and MultiAnd.controlled should return MultiAnd

related to #1271 and #1272

Why did you close this?

[NoureldinYosri]

I thought this use case doesn't follow the controlled protocol ... the _add_ctrled method for And and MultiAnd doesn't follow the expected signature from your comment #1272 (comment)

[mpharrigan]

Can you offer your thoughts on #1304 or provide context for where you want to do And().controlled()

I wrote some more here: #1304 (comment)

The contract (irrespective of whether the registers are RIGHT or THRU) is that the controlled version can only add new registers that comport with CtrlSpec.qdtypes. The system has no idea what to do with the extra junk registers. If you wanted to encode the idea that "this junk needs to get cleaned up by And^dag" you'd use something like #1221
