perf: faster page navigation by speeding up createClientConfig, speed up version fetching, speed up lexical init. Up to 100x faster (#9457)

If you had a lot of fields and collections, createClientConfig would be
extremely slow, as it was copying a lot of memory. In my test config
with a lot of fields and collections, it took 4 seconds(!!).

And not only that, it also ran between every single page navigation.

This PR significantly speeds up the createClientConfig function. In my
test config, its execution speed went from 4 seconds to 50 ms.
Additionally, createClientConfig is now properly cached in both dev &
prod. It no longer runs between every single page navigation. Even if
you trigger a full page reload, createClientConfig will be cached and
not run again. Despite that, HMR remains fully-functional.

This will make payload feel noticeably faster for large configs -
especially if it contains a lot of richtext fields, as it was previously
deep-copying the relatively large richText editor configs over and over
again.

## Before - 40 sec navigation speed

## After - 1 sec navigation speed

## Todo

- [x] Implement ClientSchemaMap and cache it, to remove
createClientField call in our form state endpoint
- [x] Enable schemaMap caching for dev
- [x] Cache lexical clientField generation, or add it to the parent
clientConfig

### Speed up version queries

This PR comes with performance optimizations for fetching versions
before a document is loaded. Not only does it use the new select API to
limit the fields it queries, it also completely skips a database query
if the current document is published.

### Speed up lexical init

Removes a bunch of unnecessary deep copying of lexical objects which
caused higher memory usage and slower load times. Additionally, the
lexical default config sanitization now happens less often.
