CI - Disables Downstream Project actions

[Lichtso]

Problem

In #32982, which in turn is necessary to upgrade Rust (see #32961), we change a public interface here in the monorepo, which is used by the SPL repo. Both repositories form a cycle of CI dependency.

Summary of Changes

Removes the GitHub action files "downstream-project-spl.yml" and "downstream-project-spl-nightly.yml".
This should be reverted once v1.17 is branched off.

i think we can be a little less intrusive with jobs.<job>.if

...
  jobs:
    job_name:
      if: false
      ...
    ...

[Lichtso]

The if clause is already used by some jobs, and I don't want to change them. This as it is, is a far more obvious revert IMO.

Is it possible to only remove the CLI jobs and general test one? This looks like it's only affecting public CLI APIs, correct?

everything that touches RemoteWallet 'cause it's grossly over constrained 🤕

That means that programs and tests are totally fine, right? Can we be a bit more selective about what we disable? We're working so hard on avoiding breaking changes in the SDK and I don't want us to slip up.

Thankfully, the remote wallet changes won't impact program developers, which is why I'm not advocating for a normal deprecation strategy.
