[FE] Fix checker of DEFAULT_ARGUMENTS_IN_EXPECT_WITH_ACTUAL_TYPEALIAS

...not reporting on companion object members as well as other
nested classes.

Annotation classes are accepted because this is how it already worked,
see other tests, for example `annotationsViaActualTypeAlias.kt`.

Test for nested annotation classes will be added in subsequent commit,
because it currently will fail in test
`TreeCompareTest.testCompareDiagnostics` because light-tree2fir
produces different tree due to a bug when converting properties
from expect primary constructor. See subsequent commit for a fix.
