RIDER-124738 refactor lightweight backend

1. Doesn't use the patch engine request execution mechanism on the frontend, instead uses separate document and text control models
2. Dynamic enabling and disabling on "lightweight.backend.enabled" registry with proper lightweight backend termination.
3. Lifetime of lightweight backend is the same as full backend while registry is enabled.
4. lightweightAppSession.service<ServiceClass>() pattern isn't used anymore, except special case for logger model case in extension listener.
5. Added separate PatchEngineEditorTestMode.SpeculativeLightweightBackendRebaseProhibited scenario for lightweight backend tests, and it's executed as patch engine test scenario for CSharpFrontendTypingAssistPatchEngineTest
6. Support default layered settings
7. Create separate lightweight-backend.TIME.PID.log and lightweight-backend.TIME.PID.log logs
8. Support RiderTestModel and test hosts in lightweight backend mode by splitting zones

(cherry picked from commit c0da247dc589713ab06994187a284480a5fb80bc)
