Make trust_dns_proto::rr::Record serializable

[mvforell]

When using the serde-config feature, I noticed that the trust_dns_proto::rr::Record is not Deserialize and Serialize. This can be achieved by adding a conditional derive to all its subtypes.

There are some deprecation warnings for crates/proto/src/rr/dnssec/rdata/key.rs, but I'm not sure how to fix them.

Everything looks good, I think changing the url serde option is the only thing to change.

I see the deprecation errors... we'll need to think about how to resolve that.

Inspired by rust-lang/rust#87454, it would be possible to do this in proto/src/rr/dnssec/rdata/mod.rs:

pub mod dnskey;
pub mod ds;
#[allow(deprecated)]
pub mod key;
pub mod nsec;
// ...

Then we could remove the other allow[deprecated] that are currently present in proto/src/rr/dnssec/rdata/key.rs.

What do you think about this?

I just put up a PR for fixing the openssl dep on windows: #1543

ok, all tests are passing. Thanks for the PR!
