src: refactor V8ProfilerConnection::DispatchMessage()
- Auto-generate the message id and return it for future use (we
can always parse the response to find the message containing
the profile instead of relying on the inspector connection being
synchornous).
- Generate the message from method and parameter strings and create
a `StringView` directly to avoid the unnecessary copy in
`ToProtocolString()`.
