Update minimum supported Rust version to 1.56.0

This change updates the minimum supported version of Rust to 1.56.0.
This version allows us to switch over to Rust edition 2021. A lot of
crates these days require somewhat more recent Rust versions in order to
build successfully and this is a first step towards reducing friction
with version bumps.
