The problem was that in K2 for some top-level script declarations we
need to add a dispatch receiver parameter (because frontend do not
assign any, but representing script as a class requires it to be the
script class) and at the same time, calls to these declarations rely on
properly set dispatch receiver parameter.
The simplest solution found is to have an additional traversal on the
relevan top-level declarations and assigning the dispatch receiver,
before running the main transformation.

NB: kotlin reflection do not see script class constructor after
this change, and it's ok, since the fact that the script is compiled
into a class is an implementation detail.
If needed, java reflection could be used to access the constructor.
the script declarations are considered public, at least because they
can be reused from another script then used with the `importedScripts`
configuration property. It also improves the compatibility with K1
scripting.
this error is not valid for scripts, where some receivers are set
later in the lowering, and it looks like in other cases this problem
will be detected later in lowering or codegen anyway.
This change allows to revert adding `WITH_STDLIB` directive
to tests which happened at `a9343aeb`.

This inconsistency is present due to not using the `// WITH_STDLIB`
in the above tests. When K1 creates the enum, it tries to generate
`entries()`, and for that it tries to load `kotlin.enums.EnumEntries`,
but this is actually an unresolved reference. K1 silently swallows it,
and proceeds.
The reason K2 doesn't fail is that in order to generate `entries()` it
simply creates the necessary `ConeClassLikeType` with the desired
`classId` instead of loading the whole `ClassDescriptor`.
The reason we can still observe `$ENTRIES` and `$entries` in K1
is because they are generated during the JVM codegen, and it
only checks if the `EnumEntries` language feature is supported. It
doesn't check if the `entries` property has really existed in IR
(by this time it's expected to have already been lowered to the
`get-entries` function - that's why "has ... existed").
The reason why the codegen doesn't fail when working with
`kotlin.enums.EnumEntries` is because it creates its
own `IrClassSymbol`.

When serializing metadata for local delegated properties, we need to
find a valid container class where to put it, and where kotlin-reflect
will be able to find that metadata at runtime. Taking just the closest
class lexically doesn't work, because in the attached test, it is a
class for a lambda which does not have metadata and thus does not have a
way to store any extra information.
So, in 1663619606 we started to look for the closest "non-synthetic"
class to store this metadata. But apparently it was missed that script
is a valid container class. In the test, this meant that no
non-synthetic container classes were found to store the metadata, so we
falled back to using the closest class anyway (see `?: this` in
`rememberLocalProperty`), which turned out to be the lambda.
After this change, metadata for local delegated property in a lambda
will be stored in the script class, just like it's stored in the file
class in the non-script case.

Initialization of companion object members (e.g., delegate properties
using provideDelegate convention) can depend on property metadata array,
which in turn can be initialized before other class members.
