This is required for downstream libraries (esp. StyledStrings) to be able to influence the display of an AnnotatedString without type-piracy. The idea here is to provide an `iterate`-like display protocol that passes style information into the implementing library, which takes that information (and a "state" from the last display update), and decides how it needs to update the output to render the string. Since AnnotatedStrings don't have a distinguished "owner" or "type" (only their annotations have types), this leads to corner cases where the "laststate" you receive might be from another library. In that case, it's the responsibility of the downstream renderer to discard the laststate information and "reset" the display state as needed.

This implements a "rendering interface" for AnnotatedString, allowing StyledStrings to influence printing without type-piracy.

Dependent on #56192, and see JuliaLang/StyledStrings.jl#100 for the StyledStrings-side changes.
This should eliminate 100% of the StyledStrings type-piracy, once implemented.
