KTIJ-20826 Approximate builder inference stub types as type parameters

This is a temporary fix to avoid crashes in FIR IDE

Of all stub types, only `ConeStubTypeForChainInference` is handled now,
so we can catch the other possible errors with stub types (in the
delegates' inference, for example)

The fix introduced in this commit should be reworked when KT-50916 is
fixed
