refactor: remove imported ops from Deno.core.ops (#22194)
This commit adds a list of ops to `runtime/99_main.js` that are currently relying on getting them from `Deno.core.ops`. All ops that are not present in the list are removed from `Deno.core.ops` on startup (they are imported from "virtual op module" - `ext:core/ops`) making them effectively inaccessible to user code. This change lowers the number of ops exposed to user code from 650 to around 260. This number should be gradually decreased in follow-up PRs.
