Fix JetKeywordToken docstrings

They were flipped.
Minor: @NotNull added
Typo fixed in the method name
scopeForVisibility replaced with containingDeclaration which is enough
Usages of expressionTypingServices from ExpressionTypingContext are replaced with injection

The basic principle behind this change is that no context object should store components.
Components should be injected instead, and contexts only carry parameters around.

Particular changes:
- resolveCallWithGivenName() and resolveBinaryCall() moved to CallResolver
- ForLoopConventionsChecker introduced to confine checking conventions for Iterator and Iterable
- ExpressionTypingComponents introduced to deliver necessary components to ExpressionTypingVisitor's
- Some static methods became non-static to get access to injected components
- ExpressionTypingUtils and ControlStructureTypingUtils became components (got state injected) to avoid passing parameters around
