`FakeOverrideBuilder.provideFakeOverrides` recursively changes overrides
for all superclasses in the hierarchy, including lazy IR, which is a lot
of extra work.
Also it leads to some tests failing in the IR fake override builder mode
because it changes correct fake overrides of Java classes to incorrect
ones. Those tests are unmuted but it doesn't mean they are fixed -- most
likely we'll generate fake overrides via IR for lazy IR too, at which
point they'll start to fail again.
This big refactoring is needed to cleanup building of overrides
mappings and prevent creating redundant intersection overrides in
cases when there is no need in them:
```kotlin
interface A {
fun foo()
}
interface B {
fun foo()
}
interface C : A, B {
override fun foo()
}
```
Before this refactoring there was next override tree:
C.foo
intersection override (A.foo, B.foo)
A.foo
B.foo
Also this commit fixes special mapping of overrides in jvm scopes
for declarations which have kotlin builtins in supertypes with
special java mapping rules (collections, for example)
This patch mutes the following test categories:
* Tests with java dependencies (System class,
java stdlib, jvm-oriented annotations etc).
* Coroutines tests.
* Reflection tests.
* Tests with an inheritance from the standard
collections.
