Use R2 bucket for duckdb libraries

[myrrc]

• Use ci-builds.vortex.dev R2 bucket as source for duckdb release and commit builds.
• Mirror release builds from duckdb github releases page. Build commits from source.
• For commit builds also try to download from R2 (useful for testing pre-release in CI)
• Gate test_geometry for duckdb under release builds only. Running it for commits means we need to bundle "spatial extension which is hard on macos due to openssl-dev symbols

Macos deployment error:

I've verified manually this works for commits, they are uploaded and used from R2 as well.
