Use rust_toolchain to pin ourselves to rust version 1.80.0 (stable) (#…

…524)

https://rust-lang.github.io/rustup/overrides.html#the-toolchain-file

After this, updating the supported version of rust will be a chore, much
like updating dependencies.  However, this also means that new clippy
and lint errors won't suddenly appear overnight, hopefully simplifying
ongoing development and maintenance.

Note also that we can eliminate the `musl` target from the Makefile as
pinning allows us to request the appropriate toolchain for the musl
target.
