Track and switch to upstream versions for rust-bitcoin and secp256k1

[ceyhunsen]

Issue Description

We switched to secp256k1's fork that introduces musig2 bindings. It is however, conflicts with the current dependencies (#405). A PR (rust-bitcoin/rust-bitcoin#3913) has been opened to solve this issue.

Tasks

Parts of the task:

• Track down the progress for secp256k1's musig PR (Add Musig2 module rust-bitcoin/rust-secp256k1#716)
• Track down the progress for rust-bitcoin's secp update PR (Update secp256k1 to 0.30.0 rust-bitcoin/rust-bitcoin#3913)
• Update our fork of rust-bitcoincore-rpc to new versions
• Update clementine's Cargo.toml with the new versions

Deadline of the Issue

indefinite

[mmtftr]

It is important to note that when rust-bitcoin/rust-bitcoin#3913 is merged, we still won't be able to upgrade due to incompatibility with rust-bitcoin = "0.33.0".

I've further tested out backporting the upgrade to rust-bitcoin = "0.32.5", but there is still more work required due to other dependencies that use musig2 (which transitively uses secp256k1 = "0.29").

This task may have more steps than outlined above due to similar circumstances as above.

I'm removing this task from the milestone due to the indefinite nature of this task.
