[zerocopy-derive] Release 0.3.0

Previously, we released a change in 0.2.1 which depends on the
min_const_generics feature, which was stabilized in 1.51. This was a
breaking change for users using compiler versions 1.50 or earlier,
which means it should not have been released as a patch release.

This change bumps the version to 0.3.0. After publishing, I will yank
0.2.1.

This change also releases zerocopy 0.5.0, which depends on
zerocopy-derive 0.3.0, since most users access zerocopy-derive via the
derives' reexports in the zerocopy crate.
