Update from_plxpr to use PlxprInterpreter base class

[albi3ro]

Context:

When from_plxpr was added, we did not have any other plxpr interpreters or frameworks for them. Now we have the PlxprInterpreter class that handles a lot of the infrastructure for converting plxpr to catalxpr.

Description of the Change:

Uses the PlxprInterpreter class to cut down on repeated code and infrastructure in the from_plxpr implementation. This also makes it to the interpreters follow the same pattern as other plxpr interpreters.

Benefits:

Possible Drawbacks:
