When encountering multiple available same named types,
resolve all of them together with corresponding extensions.
This aligns well with the current resolve behavior of classes
with the same name (see `SameNameClassesFromStarImports.kt`)
Also, add extra test for resolving the ambiguous type without
the extension function. The behavior is the same - resolve to the
both classes.
Render caret names in resolve testData, so that we don't have to guess
the indices of the carets;
it makes the multi-caret testData less error-prone.
Relevant for KT-65152 and KT-62695
The solution is not complete, since resolution of KDocs is not
fully specified and is rather tricky.
Many more corner cases are to be expected.
This solution should at least give some groundwork for the future
improvements/fixes of the resolver.
