Tracking: Upgrade shared ECC dependencies and zcash_script for zcashd 5.6.0

[teor2345]

Motivation

We need to do a routine update to our shared ECC dependencies in Zebra:

• build(deps): bump incrementalmerkletree from 0.3.1 to 0.4.0 #6836
• build(deps): bump zcash_address from 0.2.1 to 0.3.0 #6855
• build(deps): bump zcash_proofs from 0.11.0 to 0.12.1 #7107
• build(deps): bump zcash_note_encryption from 0.3.0 to 0.4.0 #6857
• build(deps): bump orchard from 0.4.0 to 0.5.0 #6854
• build(deps): bump zcash_primitives from 0.11.0 to 0.12.0 #6851
• build(deps): bump zcash_script from 0.1.12 to 0.1.13 #7151
• Remove duplicate dependencies from deny.toml once ed25519-zebra and zcashd are released #6638

These should be done together to avoid duplicate dependencies.
We might want to do incrementalmerkletree in a separate PR because it has breaking API changes.

Testing

Our existing tests cover these crates, except for the note commitment tree serialisation format in RPCs. That will need a test, ideally a snapshot test that is written based on the format before the upgrade.

Related Work

This probably needs to happen before the RPC changes, but after the first stable release.

Part of this ticket is blocked by the zcashd 5.6.0 release

I see it's already been released 😅

Hey team! Please add your planning poker estimate with Zenhub @arya2 @dconnolly @oxarbitrage @teor2345 @upbqdn

Estimation note: there are some API changes in incrementalmerkletree, see PR #6836 and maybe ticket #6642 for details.
