* Consolidate GitHub CI actions, split out Monero
build now includes the specified Rust toolchain/components.
Added a test dependencies action which grabs Foundry and Monero.
Split the Monero v14 job into a matrixed job in its own workflow flow.
It's now only run when Monero has changes.
* Correct Monero unit/integration tests run timing
Additionally tests a feature-less Monero build.
Also removes a pointless Monero file, which already should have been
removed, causing this workflow to be triggered.
* Correct exclusion and paths
Updates to FROST should re-run the Monero tests to ensure it didn't
introduce API incompatibilities.
