h3: add body_capacity() helper

Previously, quiche kept all details about the relationship between
stream capacity and writable DATA internal. This could lead to awkward
situations where quiche would report a stream as writable,
`quiche::conn::stream_capacity()` could report a non-zero value, but
`send_body()` might not send anything due to DATA frame overheads.

This change introduces the `quiche::h3::conn::body_capacity()` helper
function to help applications determine the amount of usable capacity.
