Include block header in leaf commitment

[ss-es]

This PR:

• Adds a commitmethod to the inherent impl for Leaf. Note that this method is named intentionally to conflict with commit(), from the Committable implementation for Leaf defined in the same module. This means that the compiler will reject an attempt to write leaf.commit(), forcing you to write <Leaf<TYPES> as Committable>::commit() to refer to the old commitment. Additionally, the newer commit is an async function requiring an extra argument, which should make it virtually impossible to mix up.
• Propagates upgrade_lock to every place the leaf commitment was used.
• QuorumCertificate::genesis now requires a version parameter, since the leaf commitment it uses now depends on the version.

This PR does not:

• No extra integration tests are added for this, because we expect test_success_marketplace to fail if we missed something in the leaf commitment calculation.

Key places to review:

• The main change is in types/src/data.rs -- please triple-check the new commitment carefully. All other changes are a consequence of that change.
