docs/devel/qapi-code-gen: Belatedly update features documentation

Commit 013b4efc9be "qapi: Add feature flags to remaining
definitions" (v5.0.0), commit 84ab0086879 "qapi: Add feature flags to
struct members" (v5.0.0), and commit b6c18755e41 "qapi: Add feature
flags to enum members" (v6.2.0) neglected to update section
"Features".  Make up for that.
