Fix clippy::cmp_owned for (sapling, orchard)::keys with `ConstantTimeEq` (#2184) 
* Impl subtle::ConstantTimeEq for orchard SpendingKey, use that in Eq/PartialEq

* Use constant time comparisons for secret key data where applicable

This also makes Clippy happier so that we aren't creating types just to compare.

* Fix clippy::cmp_owned for orchard::keys Eq/PartialEq

By impl'ing ConstantTimeEq for those types where leaks of the value
would compromise access or privacy.

* Make clippy::cmp_owned happy for some sapling::keys

Security: reject compact sizes greater than the protocol message limit (#2155) 
These sizes should be impossible in valid messages.
So they likely represent a memory preallocation attack.

Security: Avoid silently corrupting invalid times during serialization (#2149) 
* Security: panic if an internally generated time is out of range

If Zebra has a bug where it generates blocks, transactions, or meta
addresses with bad times, panic. This avoids sending bad data onto the
network.

(Previously, Zebra would truncate some of these times, silently
corrupting the underlying data.)

Make it clear that deserialization of these objects is infalliable.

Orchard: disable clippy warnings about comparing a newly created struct (#2117) 
In Orchard, we compare canonical Pallas bytes with a supplied byte array.

Since we need to perform calculations to get it into canonical form, we
need to create a newly owned object.
