ffi: Expose filename and formatted body fields for media captions

[SpiritCroc]

Enables clients to render media captions as per the recently merged MSC2530.

Note: Blocked on this ruma PR: https://github.com/ruma/ruma/pull/1732 - which is merged by now, but bumping ruma causes some other compile conflict right now, which should probably be addressed independently of this PR

• [ ] Public API changes documented in changelogs (optional)

Hi! Thanks for the PR, would you be willing to update Ruma as well?

Hi! Thanks for the PR, would you be willing to update Ruma as well?

Maybe I'll have a try at the weekend (I'll probably have a look at updating this PR to prepare for https://github.com/ruma/ruma/pull/1738 at some point either way), but if I remember correctly from last week, there were some compile issues with code I wasn't familiar with, so may be easier for someone else. Since I'm still somewhat of a Rust noob, I'm not planning to spend too much time on it, when it's likely that someone with better knowledge of the codebase will do that at some later point either way.

Looks like someone already updated ruma, so now the PR should already compile - just rebased it onto main to let the CI test.

Thanks for the PR! I would prefer to wait on https://github.com/ruma/ruma/pull/1738 to be merged before merging this one :-).

The PR looks sensible though and should not be impacted by https://github.com/ruma/ruma/pull/1738.
