Dedupliate `syn` (#33038)

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.
