- Eliminate the distinction between source mode and snapshot mode;
  source mode hasn't worked since the switch to Dart2, and the relevant
  engine arguments are deprecated in
  flutter/engine#7497
- Hide the need for the first argument to be the executable from clients
  of the library; this is an implementation detail of the engine API,
  and not something that each client application should need to handle
  given that the expected use case is to provide a constructed argument
  array, rather than pass through argc/argv directly.
  (As part of this change, removes the macOS code to strip Xcode-added
  arguments, for the same reason.)

This is a breaking change; clients will need to update the call to the
primary entry point, including removing the dummy first argument they
were likely providing in the arguments array.
