feat: isomorphic sockets and use eventemitter3 (#2514)

Reduces filesize by 3kb minified and gzipped or 2.8% and reduces bundler
config steps.

- Move `WSWrapper` to `@xrpl/isomorphic` to remove the need to add
mapping of `ws` to `WSWrapper` file in bundler configs
- Switch to `eventemitter3` which is smaller than `events` by almost
1kb and will not require a mapping to node's `events` in `vite`
bundling. `webpack` always automatically maps it.
    - max listeners is not a thing for `eventemitter3` so we do not
need to set it to `Infinity`. `ws` uses the native event emitter which
does still need that to be set.
- Remove `eventemitter2` which was only used in tests and was replaced
with `eventemitter3`

BREAKING CHANGE: Config for frontend bundlers has changed for `ws`.
