Better debug protocol startup/reconnect handling

[TwitchBronBron]

Currently, the debug protocol has some issues:

• the debug protocol doesn't always connect on startup. there seems to be some timing issues, or because we try to connect to the control port every 50ms perhaps we overwhelm the roku.
• pressing home on the remote will terminate the debug session, even when stopDebuggerOnAppExit is false.
• Roku OS 12.5 will completely shut down an app when it encounters compile errors in a component library (it didn't do this in prior OS versions). That also results on not seeing any compile errors in complibs when using debug protocol.

Here's the proposed solution:
Change the startup flow for a debug protocol session to do the following:

• connect to the telnet connection like usual, but leave it alive for the lifetime of the debug session
  • monitor for compile errors the entire time and emit them through the already established means. Luckily for us, the complib compile errors show up in the telnet logs even though the app shuts down
  • remove the "try connect to control port every 50ms" logic in favor of watching the telnet output for this: Waiting for debugger on 192.168.1.33:8081. Here's some sample telnet output.

• if stopDebuggerOnAppExit is set to false, then when the "app exit" event occurs, do not tear down the debug adapter protocol. instead, just tear down the io socket and control port. but keep the telnet connection alive, and keep monitoring for compile errors and the "waiting for debugger...." message, in which case re-launch the control connection and start over.
