Introduce Debug and Release configurations

The debug build creates a symlink to PSES, rebuilds PSES, does not
minify the extension and generates a TypeScript sourcemap. The release
build deletes the symlink if it exists and copies PSES, does not rebuild
PSES, minifies the extension and does not generate a TypeScript
sourcemap. This removes the manual `LinkEditorServices` step and ensures
that the developer debugging experience works well.
