An uninferred parameter stub may leak through calculation of CST(Inv<Uninferred Stub>, Nothing) into a result type.
A stub type in the result type means a type error. So we can afford recalculating
CST with stub-containing types filtered out, since its an error anyway.
This prevents stub types leakages and helps with reporting type error diagnostics.

DiagnosticsTestWithStdLib now require stdlib only.
Move test data accordingly.
The only test that required kotlin-reflect is transformed into
codegen box test.
In case of null qualifier, we should not look into any static scope
NB: factory::createCallableProcessor returns NoExplicitReceiver processor
in case of null-receiver, that makes resolving the call in the test as
`property(::key)` that matches to the property itself, thus leading to
overload resolution ambiguity

Expression type serves as a part of a key for retrieving smart cast info.
Rewriting expression type with SmartCastManager leads to incorrect processing of following smartcasts for same expression, therefore it was removed.

It's necessary because of new type substitutor is eager than odl, so
if there is a substitution of type parameter deep inside type arguments
then second substitutor wins against first
#KT-35896 Fixed
It partially reverts 7898922066
because it's not obvious that it's a safe operation
for invariant/contravariant types.
Also, there's a necessary fix in prepareReceiverRegardingCaptureTypes
to make types order stable
Otherwise test bareTypesWithStarProjections becomes flaky.
Also, the changes in bareTypesWithStarProjections.kt are also expected
because the type of the expression `coneSymbol` after the second "if" is
FirVariableSymbol<*> & FirPropertySymbol & AbstractFirBasedSymbol<*>
thus we fix D in the call `coneSymbol.phasedFir()` to FirVariableSymbol<*>
because it's the first type in the list
(see the next line after the last changed in AbstractTypeChecker)
See the test and the issue for the clarification
After the change 7898922066
the expected type for "a" in expression "foo(a)" is A<E & B<*>>
But we have the original type A<E> and smart-casted enriched type A<B<*>>
(non of them is a subtype of A<E & B<*>>)
and fail in checkTypeInternal when checking types in during completion
^KT-35844 Fixed
Treating special functions for `if`, `when`, `try`, `?:` as not accepting `Nothing` result type is incorrect.
Making so leads to cases with uninferred `Nothing` result type for inner calls and lost data flow info.
