fix(ci): Add missing getblocktemplate-rpcs feature dependencies

[teor2345]

Motivation

Zebra is missing some getblocktemplate-rpcs feature dependencies.
This might be causing build bugs like #5570.

Solution

• Add missing getblocktemplate-rpcs feature dependencies between Zebra crates
• Add a getblocktemplate-rpcs feature to zebra-chain (needed for ticket Populate transparent coinbase transaction data for BlockTemplate #5453)

Review

This is urgent because these failures are blocking other PRs merging.

Reviewer Checklist

• Will the PR name make sense to users?
  • Does it need extra CHANGELOG info? (new features, breaking changes, large changes)
• Are the PR labels correct?
• Does the code do what the ticket and PR says?
• How do you know it works? Does it have tests?

This might actually make CI worse, so we need to fix the underlying error first.

[teor2345]

These changes are needed for another PR anyway, so I'm just going to close this separate PR, because it doesn't fix anything.
