Various DAP tests are specifying their own timeouts, with values ranging from "1" to "20". Most of them seem arbitrary, but some come with a comment. The performance characters of running these tests in CI are unpredictable (they generally run much slower than developers expect) and really not something we can make assumptions about. I suspect these timeouts are a contributing factor to the flakiness of the DAP tests. This PR unifies the timeouts around a central value in the DAP server. Fixes #162523
