Separate adapter build and runtime tests in CI #15175
Description
Describe the problem
We currently have a matrix to test packages other than kit on different versions of Node. However, the Cloudflare and Netlify adapter both have runtime tests that aren't affected by the Node version. There's probably no point in running these or setting up Deno for each Node version.
Describe the proposed solution
Let's run the unit tests and project builds for the Node CI matrix but create a separate CI and command that runs those non-Node runtime tests.
