This is the last step toward removing our use of `syn` version 1. It does three things: 1. Upgrades `async-recursion` to a newer version that uses `syn` 2. 2. Removes the use of `enum-iterator` that was only used to produce a trivial list of enum names. This reduces the number of crates we dependo on by 2. 3. Upgrades `media` to a version which no longer uses `syn` 1 Fixes #33034. Signed-off-by: Martin Robinson <mrobinson@igalia.com>
