Repository: detekt/detekt (kotlin)

Issue:
Add supporting infrastructure to allow usage of `analyze` entry point in rules
## Expected Behavior
detekt-parser creates a Standalone Analysis API session that can be used by rules that require support for semantic analysis.

## Current Behavior
Semantic analysis is supported through generation of a `BindingContext`.

## Context
Required for migration to Analysis API.

Pull request description:
Closes #8047
