Prompt on breakpoints in SDK/external packages that won't be hit

[DanTup]

We have a prompt here:

Dart-Code/src/extension/commands/debug.ts

Lines 401 to 405 in 8049f0a

	hasPromptedAboutDebugSettings = true;
	const message = `You have a breakpoint outside of your workspace but debug settings are set to 'my code'. Would you like to change settings? You can also change this from the status bar while debugging.`;
	const debugJustMyCodeAction = "Debug just my code";
	const debugEverything = "Debug my code + packages + SDK";

But it only ever fires if you're set to "My Code". It doesn't detect if you're set to "My Code + SDK" and setting breakpoints in packages (eg. Flutter), or vice-versa. It would be good to handle these.
