Review: https://jetbrains.team/p/kt/reviews/13244
Motivation:
```
// Module :lib
class Foo {
val member: Int = 2
}
// Module :app
// dependencies { implementation(project(":lib")) }
class Foo {
val member: Int = 2
}
```
Before the commit:
app_Foo.expectForActual is `null`
app_Foo.member.expectForActual = lib_foo.member
After the commit:
app_Foo.expectForActual is `null`
app_Foo.member.expectForActual is `null`
If I don't fix this problem then
`CommonizerHierarchicalIT.testCommonizeHierarchicallyMultiModule`
becomes red after I fix KT-59887 in the following commits
`app_Foo.member.expectForActual = lib_foo.member` happens because we
also need to match fake-overrides (KT-63550)
I didn't measure it, but theoretically, this commit should be a
performance improvement, becuase we reuse `expectForActual` cache
Additionally, The commit breaks some other tests (e.g.
compiler/testData/diagnostics/tests/multiplatform/headerClass/actualMissing.fir.kt).
The tests will become green again, once I fix KT-59887
