rust-overlay: upgrade rust-bin to 1.78.0 (1.77.0 for x86_64-win builds) (#35)

* rust-overlay: upgrade rust-bin to 1.78.0

Upgrade rust to 1.78.0, which is the highest available version of the
stable rust-bin before a breaking change was introduced in May 2024. We
will need to debug the build failure before using a later version of
rust-overlay.

* Roll rust back to 1.77.0 for x86_64-win build

There are some issues with 1.78.0 for win64. Let's try an older version.
