^KTI-1135 In Progress
This commit prevents language version increase due to bootstrapping
problems. Compiler version X attempts to build the project with the
current version X+1 -> warning about progressive mode cannot be enabled ->
error due to -Werror -> build failure.
The customization was added for compatibility with Gradle. That isn't a problem anymore, as we don't use it from KGP and soon we will eliminate the direct dependency on kotlin-compiler from KGP.
Those classes mainly include KotlinCoreEnvironment and its dependencies
This change is needed for two reasons:
1. Splitting of some common configuration of compiler from logic of CLI
makes code structure more clean
2. There is a need to add dependency on `:analysis:analysis-api-standalone`
to `:compiler:cli`, because FIR analogue of AnalysysHandlerExtension uses
services from it. But the problems is that standalone AA itself depends
on classes for compiler configuration, which leads to circular
dependency between those modules. Extracting configuration to
`:compiler:cli-base` solves the problem
