fix(source-maps): Improve error messages and logs when working with source maps.

[chmeyer-ms]

Improve user messaging, including logs and notifications, when working with source maps.
Output resolved sourceMapRoot, localRoot, and generatedSourceRoot to the debug console on connect.
Show warning notifications when expected files are not found, like if sourceMapRoot is set but it can't find .map files or .js files, or if sourceMapRoot is not defined but .ts files are found in local root etc.

Remove inlineSourceMaps from package.json, infer inline or external from files found at sourceMapRoot. One less thing for the user to configure.

Remove special case for inline source maps when encountering /scripts/ in source folder.

TS Starter pack now works with inline source maps with a one line change in just.config.ts:

const bundleTaskOptions: BundleTaskParameters = {
  ...
  sourcemap: "inline", // <--- from true to 'inline'
  ...
};
