When expected type is known, use it as expected type for branch bodies.
While it indeed becomes different from the usual select call resolution,
where expected type is applied only after completion starts,
it helps to support, e.g. callable references resolution just as powerful
as it was in K1.
Also, in some cases where diagnostics have been changed, they become
a bit more helpful since they are reported closer
to the problematic places
cannotCastToFunction.kt test has been removed because it relied
on the case erroneously supported by the hack removed from
the FirCallResolver in this commit.

Beside some corner cases, it's already prohibited in K1 because
adaptation have a bit strange nature
(they don't represent any existing real function exactly)

The situations with conflicting type arguments normally don't provoke
any runtime problems. Also, conflicts like A<T> VS A<SomeType> aren't
valid at all. Here we decided to remove them to avoid strange
and non-actionable warnings in user code.
#KT-54411 Fixed
- Add a checker which ensures that property accesses have no explicit
type arguments. If an error on the property access's callee reference
already exists, the new error is not reported in favor of the existing
error, as the property access may have been intended to be a function
call.
- `complicatedLTGT.fir.kt`: The underlying parser issue is not yet
solved, which is why `x` is parsed as a property access with explicit
type arguments.
- `reservedExpressionSyntax` tests: This new check makes a lot of the
access expressions in these tests illegal, so valid lines have been
added and invalid lines appropriately marked with
`EXPLICIT_TYPE_ARGUMENTS_IN_PROPERTY_ACCESS` errors.

Previously (few commits earlier), it contained two versions
of receiver (lhs) generated separately for each desugaring version
that looked a bit redundant.
Now, at FIR building stage we just don't create desugaring sub-trees,
instead they are being built during bodies transformation and that seems
to be much convenient there, since we don't need to reverse-engineer
get-set-operator version to check if containing calls are successful
(as we just built those calls and retain them)
Semantically, this changes may only change how data flow works
for such statements (see changed compatibilityResolveWithVarargAndOperatorCall.kt)

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.
This directive anyway does not make test run twice with OI, and with NI
It only once run the test with specific settings (// LANGUAGE)
and ignores irrelevant (OI or NI tags)
