Cyberpunk: forced load libraries instead of RB

[ZashIn]

Remove RootBuilder support/requirement (for CET and RED4ext) in favor of forced load libraries: CET and RED4ext will be installed normally via USVFS instead into root folder for RB.

Here is a test release for the current MO v2.5.2.

This needs to be tested on larger mod lists for stability! Additional discussion: https://github.com/CDPR-Modding-Documentation/Cyberpunk-Modding-Docs/pull/37

TODO:

• [x] Dialog to convert existing mod lists using RB for CET and RED4ext
• [ ] After release: update wiki with simpler installation
  • [x] Add info for CrashReporter with CET and VFS
  • [ ] Remove / move RB requirement and instructions

Extras (in separate PR?):

• [ ] Simplify load order handling, by changing defaults and notifying / converting old mod lists
• [ ] fix profile specific save files (existing ones are not moved or similar)
