chore: Remove BaseControllerV1

[MajorLift]

Explanation

Removes the deprecated BaseControllerV1 and its associated types and methods, replacing them with the V2 BaseController, its derived classes, and helper methods.

This is the culmination of work completed over multiple quarters, and represents a major step forward for performative and best practice-compliant state management in our clients.

Woohoo! Looks great to me! (edit: oh, aside from the conflicts, boo. I will keep an eye on this PR then)

LGTM! We want to merge this change along with the removal of Old Messenger Aliases, which is currently in draft: MetaMask/core#5260.

Good call @cryptodev-2s, I'm going to mark this as DO-NOT-MERGE until that PR is ready to merge.
