Change the CI --all-features to an explicit list.

This is due to the mutually exclusive features in rkyv which
we expose now. `--all-features` will now activate them and the crate
will fail to compile rkyv. We work around this by defining
an explicit list of all mutually exclusive features to.

Unfortunately there isn't an easy way to share env variables
among different YAML files
(actions/runner#655).

There also isn't a good way to specify `--all-features` minus
"just a few" (rust-lang/cargo#3126)
aside from giving the complete list.
