serve all in-crate js files

starting with rust-lang/rust#59776, the search index, aliases, and
source file list are getting the resource suffix added to their file
names. this means we can't route them from a static path any more.

since we always check the static file router first, this will still
allow serving `main.js` for rustdoc versions prior to the addition of
`--static-root-path`, and also allows rustdoc to add per-crate
javascript files without requiring docs.rs to update to handle it.

(it also allows us to start hosting things *other* than rustdoc output
as docs - e.g. mdbook output - in the future without changing the
routing table massively.)
