add pass_name to transforms

[albi3ro]

Note that doctest will be failing till we update the corresponding catalyst PR. I decided to just leave it failing for now so I don't have to go back and fix it after the catlayst PR goes in.

Context:

Exploring how to better unify pennylane transforms and catalyst passes. Will have matching catalyst PR.

Thanks a lot for doing this 😁! Made some comments on the docs :)

Looks good to me! I'll let Isaac have the final say in the documentation-related stuff as there is already lots of ongoing discussion about that.

Thanks a bunch for this! One more discussion to be resolved (https://github.com/PennyLaneAI/pennylane/pull/8539/files#r2578665674) but it looks great :)
