Revert "Accept references for set_contents"

When using generic in a trait the trait becomes not object-safe forcing
generics or static dispatch in a such code. For a crate like copypasta
that's something we don't really want to, since it's usually
self-contained and has different clipboard providers.

This reverts commit 10f1137.

 `ClipboardContext` is a type alias for one of {`WindowsClipboardContext`, `OSXClipboardContext`, `X11ClipboardContext`, `NopClipboardContext`}, all of which implement `ClipboardProvider`. Which concrete type is chosen for `ClipboardContext` depends on the OS (via conditional compilation).
