Should fix messed up import suggestions and simplifies all tsconfigs
through inheritance.
One main issue was that packages were inheriting `baseURL: "."` from the
root tsconfig. This caused incorrect import suggestions that start with
"packages/...".
This PR ensures that packages do not inherit this baseURL: "." property,
while ensuring the root, non-inherited tsconfig still keeps it to get
tests to work (the importMap needs it)
This noticeably improves performance in the admin panel, for example
when there are multiple richtext editors on one page (& likely
performance in other areas too, though I mainly tested rich text).
The babel plugin currently only optimizes files with a 'use client'
directive at the top - thus we have to make sure to add use client
wherever possible, even if it's imported by a parent client component.
There's one single component that broke when it was compiled using the
React compiler (it stopped being reactive and failed one of our admin
e2e tests):

opting out of it completely fixed that issue
