Basically, this commit reworks eraseToUpperBound* stuff
Instead of a bunch of vague flags, we introduce two modes
(rawTypes/intersection emptiness checker) which defined those flags.
Also, it makes choosing `eraseArgumentsDeeply` option always because
that how it works in K1 and also use invariant projection inside
`eraseArgumentsDeeply` for raw types for the same reason.
^KT-57198 Fixed
When suspend function type is serialized, there is special logic that
adds Continuation parameter, before doing so, type-aliases has to be
expanded, attributes for resulting type should also derive from
expanded type

Before this commit, we added Enum.entries only in case when
LanguageFeature.EnumEntries was ON (with an exception in K1/Java case).
In this commit we add Enum.entries unconditionally, and in case
the language feature is OFF we filter them out during tower resolve.
In DeserializedClassDescriptor and MemberDeserializer, only the
`contextReceiverTypeList` field was used, and not
`contextReceiverTypeIdList` which is used when `-Xuse-type-table` is
enabled. The convention is to use a bunch of utilities declared in
`protoTypeTableUtil.kt` which deal with both methods of reading types.
Also, simplify the deserialization code in FIR (which was correct for
some reason).
This is a partial revert of e857966edb.
Specifically, behavior is restored in the old backend, which will allow
to support language version 1.3, where this language feature was not
enabled yet. There are no changes in the JVM IR backend, because to
enable JVM IR with LV 1.3, you need to pass the compiler argument
`-Xuse-ir` which is not stable and we don't guarantee anything about it.

so that defaults are available to synthetic implementations.
#KT-48181 Fixed
Implementation is for JVM IR; other backends & FIR need to be supported
separately.
If some java class has multiple supertypes then we need to collect
overriddens from all those types directly, even if superTypeScope
(which is FirTypeIntersectionScope in this case) returns only
one symbol from one of this types (not intersection one)
This is needed to proper enhancement in cases when some type occurs
multiple times in supertypes graph with different nullability
of arguments:
class ConcurrentHashMap<K, V> : AbstractMap<K!, V!>, MutableMap<K, V>
If we try to find method `get(key: K): V` supertype scope returns
`AbstractMap.get(key: K!): V!` (because it actually overrides
`MutableMap(key: K): V?`), but we need to get both symbols to
properly enhance types for `ConcurrentHashMap.remove`
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.
1. Inner class constructor should have its outer class as a dispatch
receiver, since it is necessary for the call. Before it was null
2. Substituted inner class constructor should have its original dispatch
receiver type with the proper substitution. Before it was set to the
class itself (since the class was usually passed as a new dispatch
receiver)
Also, modify FIR renderer, so it properly renders the dispatch receiver
of the constructors
Because those test are single Java files, many of them use a top-level
class as a container for multiple classes to be tested. Such tests do
almost nothing if those nested classes aren't handled.
