Jack Grigg d6897cc8c1 zcash_note_encryption: Clean up dependencies 
Several dependencies were copied over during the extraction of this
crate's logic from `zcash_primitives`, but are in fact only required for
the protocol-specific logic. We can also remove the `std` feature flag,
since we no longer have a dependency on `blake2b_simd` that needs its
`std` flag exposed for performance.

Jack Grigg 9994ddc70d zcash_note_encryption: Constrain outgoing ciphertext size 
This replaces a length assertion, making the API more predictable.

Jack Grigg 1ac6d5b8fe zcash_note_encryption: Constrain `ShieldedOutput` ciphertext size 
Previously we were returning the ciphertext as a slice, and then
asserting its length within the APIs the caller passed it into. Now
instead we require the caller to define whether or not the output is
compact, to make the API more predictable.

This doesn't place any additional constraints on users of this trait,
because the assertions already prevented a full output from being passed
to a compact trial decryption API.

Jack Grigg 7ab76d8574 zcash_note_encryption: Remove `Domain::check_epk_bytes` 
`Domain::derive_esk` provides sufficient information to determine
whether or not we need to enforce `EphemeralSecretKey`-specific
decryption checks, as it returns `None` for pre-ZIP 212 notes.

Jack Grigg 34277d4e38 zcash_note_encryption: Use `*PlaintextBytes` structs in `Domain` APIs 
`Domain::parse_note_plaintext_without_memo_ivk` is used with both full
note plaintexts and compact notes, so continues to accept a slice. For
all other `Domain` APIs, we constrain the input to `NotePlaintextBytes`
or `OutPlaintextBytes` as appropriate.
