Remove catalog tests out of monorepo

[richardhjtan]

To be merged after this PR cardstack/boxel-catalog#19 goes in

What is changing

• remove catalog realm involved related tests
• skip catalog realm when doing host test
• the SKIP_CATALOG is still needed because boxel-catalog can remove the variable and run the catalog realm test in CI
• rename start-all-except-experiment script -> start-all-except-optional

Preview deployments

• Host staging preview
• Host production preview
