Move Fetch API releted code to modules/fetch.

Move Fetch API releted code to modules/fetch.

Fetch API related code is located on modules/serviceworkers because of a
historical reason. Now fetch() function is planned to be exposed to
other global scopes and it is natural to have a dedicated directory.

modules/serviceworkers depends on modules/fetch.
