Bump required dependency versions

To minimal versions required to build most features (all other than core
and rustc-dep-of-std) with --all-targets.

Minimal required versions discovered by manual binsearch between
minimum compatible version declared currently and the newest one
available, and rerunning

  cargo check --all \
    --features serde,arbitrary,bytemuck,std,example_generated \
    --all-targets -Z minimal-versions

to verify if it builds.
