Always include Cargo.lock in published crates

Originally it was only included for packages that have executables or
examples for `cargo install`, however this causes inconsistencies and
is kind of unexpected nowadays, e.g. with cdylib crates.

Including it always only slightly increases the crate size and allows
for all crates to know a set of dependency versions that were working,
which can make regression tracking easier.

Fixes #13447
