feat: embed import map in the config file (#17478)

This commit changes handling of config file to enable
specifying "imports" and "scopes" objects effectively making
the configuration file an import map.

"imports" and "scopes" take precedence over "importMap" configuration,
but have lower priority than "--importmap" CLI flag.
