Align default transform profile Babel preset with legacy Hermes - drop "older" engines (#54806)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/54806

Align the default transform profile in our Babel preset with the current state of `hermes-stable`, drop non-Hermes, pre-ES6 engines which have been unsupported in core since the JSC removal.

This will allow us to subsequently repurpose transform profiles (`unstable_transformProfile`) to remove transforms unnecessary for Hermes v1 (aka Static Hermes) as follows:

- `hermes-canary` -> Hermes v1 (experimental features)
- `hermes-stable` -> Hermes v1
- Default -> All supported engines (i.e, Hermes v1 and legacy)

Changelog:

[General][Removed] Remove Babel preset transforms for already-unsupported non-Hermes engines
