Account for JsExport in legacy backend namer. It means we
catch overloaded exported function conflicts for free!
Add error diagnostics:
* NESTED_JS_EXPORT (Fixes KT-36798)
* WRONG_EXPORTED_DECLARATION (Part of the fix for KT-37752)
* NON_EXPORTABLE_TYPE (Fixes KT-37771)
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

When we generate call for 'foo', we make decision about invoking
a 'foo$default' too late, after the call arguments are generated.
If 'foo' was an override, and base class (interface) was generic,
'foo' in base class could have a different Kotlin and JVM
signature, so the arguments we generated could be generated wrong
(primitive or inline class values instead of boxes, see KT-38680).
Also, we always selected first base class in supertypes list,
which caused KT-15971.
Look into resolved call and see if we should actually call
'foo$default' instead of 'foo' when determining actual callable.
Overrides can't introduce default parameter values, and
override-equivalent inherited methods with default parameters
is an error in a child class. Thus, if we are calling a class
member function with a default parameters, there should be one
and only one overridden function that has default parameter values
and overrides nothing.
A follow-up for KT-35006:
fun f() = foo {
bar()
}
inline fun foo(crossinline x: () -> Unit) = { x() }()
inline fun bar() = TODO()
does not provide the option to navigate to bar's call site at all.
* a writing source mapper has `mapLineNumber(line, file, class)` that
inserts a new SMAP entry and returns a fake line number from it;
* a copying source mapper has `mapLineNumber(line)` that uses an
existing SMAP to resolve the line number and call the former method
on a different source mapper;
* those two types are disjoint.

The idea is that dispatch receiver is available there in old FE, but additional
diagnostic should be reported on it (see KT-38813)
This change was not made intentionaly but it was the easiest way to
support new tower data elements structure and on the other side it's the
correct behavior as for old FE.
Also, if we once would prefer the previous behavior it's still not very
hard to support it
Unbound it from implicit receiver stack as it only needs scope structure/declaration nestedness
Semantics for protected has been changed in a way it works in old FE
NB: We should report additional diagnostic in case of CallCompanionProtectedNonStatic.fir.kt
(see KT-38814)
In case of IrFunctionReference with type SuspendFunction (no K!) there
was a misalignment between the base class (Any) and the
origin (LAMBDA..). As a result the SuspendFunctionLowering was
getting confused and produced hanging code.
Before this commit we considered !isOverride as a sign that
function / field / accessor has no overridden symbols.
However, it's false for deserialized, because isOverride
is always false there.
