In this example we get 2 variants of `kotlin/toString()`:
one coming from the KLib provider, and the
other coming from the builtins provider.
These are identical deserialized functions.

Current qualified access resolving algo rely (likely incorrectly,
see #KT-58037) on a providers' "knowledge" about parent packages.
This commit adds this "knowledge" to k-lib based provider.
#KT-57353 fixed
This fixes an issue where an actual class from an intermediate module
has more supertypes than its expect declaration which leads to a
false-positive resolution error because a type reference resolves to the
expect class. The fix is to sort the dependencies topologically from
"most actual" to "most expect" when creating the list of symbol
providers.
#KT-57369 Fixed
In a lot of cases, when we want to process the
declaration in scope, it should be resolved to at least TYPES phase.
To avoid doing it manually in all our variety of scopes, we do it when the scope it created.
It was implicitly working manually before as lazy resolve did a lot of extra work
on resolving a declaration it was not supposed to resolve.
Now it's not the case, and we have to explicitly resolve all the declarations we need.

- This optimization applied to LL FIR can be extended to K2 as a whole.
Likely, there won't be any performance benefits in CLI runs, but it's
still better to avoid useless symbol providers.
with dedicated opt-in language feature and special
annotation or module capability.
Not intended for a general use, solves specific K/N
scenario with interop libs.
#KT-55902 fixed
`supportsEnumEntries` in `EnumCLassLowering` is not really
needed, but it was left just in case.
Both K1 and K2 ensure the feature is
enabled before they generate IR.
`supportsEnumEntries` is not enough, because the frontend will not
generate `entries` if `kotlin.enums.EnumEntries` is not available
(linking against an outdated stdlib is considered a valid use-case).
From the resolution point of view,
it's OK to resolve into `entries` while
the feature is off, because then K1 reports an error on the call site.

It's been introduced in the previous commit
("K2: Simplify handling mixed smartcast vs. original candidates")
Because previously, it was assumed wrongly that each next level of
ConeCallConflictResolver filter out the candidates that are 100% less
applicable/specific, but the main one (ConeOverloadConflictResolver)
either leaves the single candidate or the whole same set, thus at
FilteringOutOriginalInPresenceOfSmartCastConeCallConflictResolver
we've got 4 candidates only two of which we might filter out.
The idea is that when we have successful candidates both from smart cast
and original type, we should discriminate in the favor of former ones.
While this problem (see kt55722.kt) existed before this branch is merged,
initially it was recognized on FP Ultimate when we stopped assuming
captured types from the same projections as equal (see kt55722Initial.kt).

Support importing synthetic declarations from "magic" forward
declaration packages:
- cnames.structs
- objcnames.classes
- objcnames.protocols
So this is a rough equivalent to the forward declarations module
made of ForwardDeclarationsPackageFragmentDescriptor in K1.
Unlike K1 implementation, this K2 one doesn't allow importing
a declaration that wasn't actually forward-declared in a C/Objective-C
header available through a cinterop klib dependency.
This is needed because now set of available synthetic functional interfaces
depends on session, because each module can contain different plugins,
which provide different kinds of functional types
This is needed to provide an ability to extend different kinds of
functional types
Also, cleanup and rename utilities related to functional types to avoid
possible confusions
