Update MSRV to 1.73

A MSRV update is required to update the image crate to 0.25, otherwise
we get link error that are ficed in newer version.
Also other dependency update such as env_logger needs a newer MSRV.

Update to 1.73 because it has functions like `with_borrow` on thread
storage which we already actually use in some platform.

This is also the last release before the the drop of macOs < 10.12
in Rust 1.74
