[YOCTO #15808]
Consolidate Rust source management across all Rust recipes (rust, cargo,
libstd-rs and their native/nativesdk variants) into a single shared
source tree using the work-shared pattern.
Disk savings: a world build with multilibs enabled, together with
nativesdk-rust and nativesdk-cargo, now shares a single ~4.2 GB rustc-src
tree instead of maintaining up to 11 independent copies (~46.2 GB total).

Fixed in v3.
