[Macro] Add a new macro loading option that do not involve searching

Browse Source 
Add flag `-load-resolved-plugin` to load macro plugin, which provides a
pre-resolved entry into PluginLoader so the plugins can be loaded based
on module name without searching the file system. The option is mainly
intended to be used by explicitly module build and the flag is supplied
by dependency scanner.
