This introduces the `denort` binary - a slim version of deno without
tooling. The binary is used as the default for `deno compile`.
Improves `deno compile` final size by ~2.5x (141 MB -> 61 MB) on Linux
x86_64.
This commit moves all Chrome Devtools Protocol messages to `cli/cdp.rs`
and refactors all places using these types to pull them from a common
place.
No functional changes.
