Bump MSRV for `zcash_primitives` and dependents to 1.60

The MSRVs of the component crates are left as-is, partly because our
dependencies don't require us to bump them, and partly because those
crates have no pending changes and are relatively stable. We also plan
to split the component crates out into a separate repository, where it
will be easier to have a separate MSRV.

Closes zcash/librustzcash#759.
