Subject: [PATCH] rustdoc-json-type: Depend on `serde` and `serde_derive`
 seperately

Before this commit, serde_derive is built before serde. But serde does
not depend on serde_derive, so that is not needed. Instead, build serde
and serde_derive in parallel.

This speeds up compilation for users depending on rustdoc-json-types out
of tree.
