If we want to analyse some function's call, we need to know about its
contracts, otherwise resolving the following code would be broken.
Computing return type of function is a prerequisite to using it in any
sensible way, so it's the best place to resolve it to CONTRACTS

Extension receivers are currently implicitly noinline, and changing that
would require modifying the syntax to allow marking them noinline or
crossinline.

class JavaSuperClass {
// members impls with special signature, but it doesn't override any Kotlin specials
}
class KotlinInterface {
// special members
}
class JavaSubClass extends JavaSuperClass implements KotlinInterface {
// we should obtain members from JavaSuperClass with their Kotlinish
// signature, not the Java one
}
That issue might be fixed via changing
TypeVariableMarker.shouldBeFlexible at ConeConstraintSystemUtilContext
but this and some other tricks have been added because of incorrect
handling of constraints where type variable has a flexible bound

In this commit we upgrade FIR builder inference logic from
the compiler version to 1.7. FIR-based compiler now works with
"don't use builder inference" flag always ON and supports switching
the flag "use builder inference only if needed". To do it,
ContraintSystemCompleter (FIR) and KotlinConstraintSystemCompleter (FE 1.0)
are made similar with extracting some common parts into
ConstraintSystemCompletionContext.
Test status: one BB test fails after this commit (KT-49285).
Also we have a crush in DFA logic in FIR bootstrap test and somehow
questionable behavior in FIR diagnostic test. However,
two BB tests were fixed, the 3rd case from KT-49925 were also fixed.
#KT-49925 Fixed
Previously enhanced symbols were cached inside SignatureEnhancement,
which is created independently for each enhancement scope. This may
cause creation of multiple enhanced symbols for same java declaration
in presence of multiple scope sessions (mutithread compiler, IDE,
separate scope session for checkers)

This big refactoring is needed to cleanup building of overrides
mappings and prevent creating redundant intersection overrides in
cases when there is no need in them:
```kotlin
interface A {
fun foo()
}
interface B {
fun foo()
}
interface C : A, B {
override fun foo()
}
```
Before this refactoring there was next override tree:
C.foo
intersection override (A.foo, B.foo)
A.foo
B.foo
Also this commit fixes special mapping of overrides in jvm scopes
for declarations which have kotlin builtins in supertypes with
special java mapping rules (collections, for example)
Mostly, it only affects FIR
It partially allows to consider several variance of constraints like
A<Int> & A<T> <: A<X_var> that are mostly brought by smart casts

There just should be a different facades for cases
A<T1, T2> and foo<T1, T2>()
Test data has changed for type alias constructors since previously,
it was working by mistake because of assumption that type alias arguments
are linearly mapped to the type parameters of the corresponding constructors
