[P2] Fixes Transform/Imposter not updating type/battle stat changes immediately; set move PP to 5 when transforming (#3462)

* Adds updateInfo to transform move/ability, mirrors Transform functionality in Imposter

* Implements functionality for reducing pp to 5 or less for each move when transforming

* Refactors to async/await pattern, adds back removed anims/sounds from last commit

* Eslint fix attempt

* Update src/data/ability.ts

per DayKev's suggestion

* Merge and fix conflicts

* Adds unit tests for pp-change with transform/imposter

* Updates to consistency in syntax/deprecated code
