EVM Node: Use a dedicated rust_deps

Having a dedicated rust_deps foreign archive is not strictly necessary for the Octez EVM Node to support native execution of kernels, but considering it remains a nice to have to avoid cluttering build times of other engineering time. Additionnally, it allows to remove the dependency to the RISC-V PVM until it is not strictly necessary (it will obviously be possible to re-introduce this dependency later, when it makes sense to do so). Finally, it will allow us to experiment with using more recent version of Wasmer without impacting the Rollup Node.

The changeset proposed here might seem large, but it is in part because it affects a lot of files generated automatically.

Strictly speaking, the change is really similar to what has been done for the Octez Node previously with the rustzcash_deps library. But it does introduces a challenge:

• rust_deps does not contain the WASM Runtime anymore.
• etherlink/bin_node/test tests have a dependency to the Octez EVM node library (lib_dev) which does have a dependency to the WASM Runtime.

As a consequence, the unit tests of the Octez EVM Node cannot be linked to the main tezt binary. This is why we propose in this patcheset to turn these tests into old school unit test, executed in a dedicated job to be aple to set a narrowed changeset.
