Juan Chen 4f6fe1d0ca [FIR]: fix translation of top-level property accesses like array.indices
This commit addresses the following issues:

* accessors didn't take into account their property's receiver type,
which caused NoSuchMethod due to signature mismatch. Now the property's
receiver type is passed to Fir2Ir translation of accessors.

* property's parent was not class, e.g., kotlin.collections.indices.
Now the symbol table collects WrappedPropertyDescriptorWithContainerSource
besides WrappedFunctionDescriptorWithContainerSource, so that
facade classes for such properties can be generated before codegen.

* accessor's parent was not class. Now the containerSource of
the property descriptor is passed to accessor descriptor.
