[Analysis API] Add API for code compilation

The API replaces 'KotlinCompilerIde' in the IntelliJ IDEA plugin.
Code moved to Analysis API as its K2 implementation severely depends on
the internal compiler API (FIR).

The API is going to be used in the JVM debugger evaluator, and in
the Bytecode Tool Window.

In this commit, only ordinary Kotlin are supported.
In later commits, there will be also support for 'KtCodeFragment' files,
as well as some test coverage.
