Patched out forcing references in query arguments

[Buzzec]

Is this a breaking change?

This is a breaking change, it makes arguments no longer forced to be references. Users will have to manually reference their arguments.

Reasoning

This allows returning owned values as part of outputs, such as a function that outputs a stream from a fetch call can have values that are passed to that function as args.

We are already using this patch in our large codebase as it allows for optimized returns for streams.

Users will have to manually reference their arguments.

This is a net negative for most usages. We deliberately designed the macros not to require manual references because that's really surprising compared to macros like println!(), etc.

This really needs to be a part of a larger conversation where we decide whether to drop the borrowing from Encode entirely.
