RFR: 8318072: DonwcallLinker does not acquire/release segments in interpreter

[Jorn Vernee]

Implement missing by-reference argument acquire/release functionality in DowncallLinker::invokeInterpBindings.

I've also simplified the related code a bit:
- `retIndexMap` was not used. I've removed it
- `BindingInterpreter.StoreFunc::store`'s type argument was not used. Removed
- UpcallLinker was redundantly collecting the move bindings for return values. Removed

I've added runs without specialization to the failing tests as well, so that we keep testing this.

Testing: `jdk_foreign` suite.
