This commit solves a stub type inconsistency problem.
As a part of KT-59369 fix we decided (see commit 299d2799),
that ConeStubTypeForChainInference has a scope of Any,
so we can safely resolve only to equals/hashCode/toString.
However, later we can replace a stub type with some inferred type,
which can have its own equals/hashCode/toString implementation,
while the call still refers Any member.
In this situation FIR2IR decides that we are calling a fake override,
which is not true, in fact we are calling an overriding method.
This leads to a crash in Native backend.
To solve this situation, we provide an explicit cast of a dispatch
receiver with a stub type (ConeStubTypeForChainInference) to Any,
thus confirming directly we are calling Any method and nothing else.

- Actualize muted K2 tests
- Actualize muted K1 tests with module systems because legacy Wasm test
infra had no respect for "// MODULE: ..." test directives
When BI/incomplete call is present in return argument, it will be
added to the main call-tree, leading to requirement violation in
`ConstraintSystemCompleter.getOrderedAllTypeVariables`
as after `FirBuilderInferenceSession.inferPostponedVariables` it will
be completed, and its type variables couldn't be found anymore
In K1, we actually do the same, but we are able to find type variables
of such calls due to architecture difference:
In K2, `getOrderedAllTypeVariables` uses FIR as the main source to
lookup
In K1, `getOrderedAllTypeVariables` uses resolution atom tree, where
candidate/CS of the call is still available after
`inferPostponedVariables`
In fact, all incomplete calls were analyzed in FULL mode according to
the contract of `FirBuilderInferenceSession.addPartiallyResolvedCall`.
Thus, it means we normally shouldn't add them to the main call-tree, but
accidentally do it as incomplete calls contain non-completed candidate
This particular commit addresses the problem partially, only
in cases when the expected return type for the lambda is Unit and when
the incomplete call is located in the last expression of the lambda
In such cases, we can skip the call from the last expression completely,
since all potential calls there were analyzed in FULL mode,
and couldn't introduce any useful info to the CS of the main call-tree

Previously, updateTypeInBuilderInference was calling
updateTypeFromSmartcast to actually perform type update in
implicit receiver after stub types was inferred
Such action results in creation of following FIR:
FirSmartCastExpression(
original=FQAE(FirImplicitThisReference, typeRef=R|Inv<Stub>|)
typeRef=R|Inv<String>|
)
in receiver position during completion of calls
However, it wasn't the case in general situation due to
action of FirStubTypeTransformer, which, in turn visits and updates
type ref inside original expression, but only if there was at
least one call (that was completed) using that implicit receiver
As after such type update updateTypeFromSmartcast function does
nothing
Yet in situation, when there was only partially resolved calls
referencing that implicit receiver we actually create smart-cast
expression and don't update type
The change just removes usage of updateTypeFromSmartcast and
replaces is with direct type update
We still mutate state of implicit receiver, potentially
improperly, it should be addressed in future

^KT-58365 Fixed
It's reported on receivers in extension function calls with stub type,
as such calls can shadow members of finalized stub types causing
change of resolve when corresponding type argument specified explicitly
It works by checking extension receiver during call resolution parts run
That way we can easily detect if we found an extension applicable to
stub receiver and report call diagnostic for it

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
We are going to deprecate `WITH_RUNTIME` directive. The main reason
behind this change is that `WITH_STDLIB` directive better describes
its meaning, specifically it will add kotlin stdlib to test's classpath.
