Fix compilation errors, revealed by this fix.
SmartCastManager is unnecessary for error reporting, intermediate diagnostics from the NI contain all required infromation.
When SmartCastManager is used it leads to missing unstable smart casts in case of expressions with captured types.
This happens, because data flow info is recorded for original expression without captured types, which is used as a key.
DataFlowValues created from receivers with captured types can't be used to retrieve that info.

- Allow participating subtypes of functional types in conversions
- Fix several subtle inconsistencies
- Place logic about conversions at one place
Now conversions operations have two stages: before usual subtyping
check and after one. This is needed to support conversions of
subtypes (of functional types, for example). First, the compiler
checks if it possible to resolve an argument without conversion and
only then it tries to perform conversion.
Note that it'd be incorrect to perform conversion eagerly as it can
change resolve (Runnable & () -> Unit <: KRunnable), plus we can't
guess whether conversion is needed at all as it's important not to
look into supertypes if resolution doesn't actually needed it

Before this change:
- Local scopes, implicit receivers and type parameter scopes were separated.
- Static scopes for super classes were not present as a concept.
Instead of them, all-inherited-static for the current class has been used.
- During call resolution we were processing implicit receivers first and then non-local scopes,
while we should process them in the order of their syntax appearance from the closest
to the most distant
All these facts affect semantics (see test data changed here and the following commits)
The architecture changes are the following:
- FirTowerDataElement introduced as tower level that is used in resolution
(effectively it's a union type between scope and implicit receiver + isLocal flag)
- FirTowerDataContext introduced for sake of encapsulation of tower data elements' list
(it also has redundant implicitReceiverStack and localScopes)
- For each regular class we collect relevant tower data elements and add them to the current context
- Also, we preserve a special tower data context for static entities of the class
(it doesn't have class' dispatch receiver and generic parameters)
For single super type constructor create star projection argument when types for that argument are equal to the original types.
Captured star projections are replaced with their corresponding supertypes during this check.
Skip check for `in` parameters, for which recursive cst calculation does not happen.
Adjust constant in fallback recursion condition.

Introduce seven stages:
1) Analyze postponed arguments with fixed parameter types
2) Collect parameter types from constraints and lambda parameters' declaration
3) Fix not postponed variables for parameter types of all postponed arguments
4) Create atoms with revised expected types if needed
5) Analyze the first ready postponed argument and rerun stages if it has been analyzed
6) Force fixation remaining type variables: fix if possible or report not enough information
7) Force analysis remaining not analyzed postponed arguments and rerun stages if there are

This is needed so that it wouldn't clash with the corresponding member
from the kotlin/jvm/internal/FunctionAdapter interface, which all fun
interface wrappers will implement to get proper equals/hashCode. The
workaround is to rename the fun interface method.
