This is necessary in order to provide criterion-specific arguments to
`cargo bench`, such as `--profile-time`.

zcash_note_encryption: Add `ShieldedOutput::ephemeral_key() -> EphemeralKeyBytes`
...
This replaces the `ShieldedOutput::epk() -> &Domain::EphemeralPublicKey`
which could not be satisfied by output types that did not parse epk.

- nom is part of the funty breakage; we are blocking on a new release.
- orchard is in development.

zcash_note_encryption: Fix array size in Domain::extract_{esk, pk_d}
...
Decrypted output size is `OUT_PLAINTEXT_BYTES`, which the decryptor
can always provide (either by decrypting into the correct size array
as now, or truncating the buffer before passing it to the domain).

zcash_note_encryption: s/TryFrom/From on ExtractedCommitmentBytes bound
...
This was left over from an earlier refactor where we could call a domain
API to extract cmstar from a note commitment (which could fail for
Orchard). This part of extraction was subsequently refactored into the
domain logic (and is rejected earlier for Orchard). The resulting bound
is wrong because it's always possible to serialize a scalar.

Use ShieldedOutput trait for note encryption/decryption.

This change modifies note encryption and decryption functions
to treat a shielded output as a single value instead of handling
the parts of an output as independent arguments.
