Update to 1.13.0.

- Use hardening flags for linking.
- Split the standard library into its own package
- Centralize rustlib/ under /usr/lib/ for multilib integration.

-    
-    rustc: Don't enable NEON by default on armv7 Linux
-    
-    One of the primary platforms for the `armv7-unknown-linux-gnueabihf` target,
-    Linux distributions, do not enable NEON extensions by default. This PR disables
-    that feature by defualt but enables the `d16` feature which enables VFP3D16 that
-    distributions do enable.
-    
-    Closes #35590
