Switch to serde-enabled rls-* and update RLS appropriately

This also bumps RLS version to 1.36.
The updated rls-* packages use serde but *not* serde_derive thanks to
manual proc macro expansion. This is a hack, since rustc cannot handle
crates.io proc macros (duplicated in tools) when cross-compiling, so
that's the best we can do in order to support serde_json in save-analysis.
