a57aff04c9 [cxx-interop] Avoid generating ambiguous wrapper functions
When we generate a safe wrapper that only differs in the return type we
might introduce ambiguities as some callers might not have enough
information to disambiguate between the overloads. This PR makes sure
the newly generated declarations are marked as @_disfavoredOverload so
the compiler can keep calling the old functions without a source break
when the feature is turned on.

fdea6ba8d0 [Swiftify][ClangImporter] Import noescape attribute for parameters (#78713)
This passes along the noescape attribute to @_SwiftifyImport as
.noescape(pointer: .param(X)). This allows importing parameters as Span,
MutableSpan and RawSpan.

e252cbbaeb [SwiftifyImport] Add sizedBy support for OpaquePointer (#78315)
This makes it possible to mark a pointer with __sized_by when the
pointee type definition is not included. The wrapper function has the
same interface as if the parameter were a void pointer, since the stdlib
has no `OpaqueBufferPointer` type.

* use swift-ide-test for checking interop signatures
* add xfail test for Span + Optional combo (Optional requires Escapable)
