[Diagnostics] Treat type requirement failures associated with Self = Any as unrelated

Browse Source 
This helps us to filter out cases like operator overloads where
`Self` type comes from e.g. default for collection element -
`[1, "hello"].map { $0 + 1 }`. Main problem here is that
collection type couldn't be determined without unification to
`Any` and `+` failing for all numeric overloads is just a consequence.
