Initial stub version of Async Clipboard API

third_party/WebKit/LayoutTests/W3CImportExpectations

 # This file controls which subdirectories of the w3c test repos we import.
 #
 # This file acts as a blacklist; directories and files not listed here will
 # automatically be found and imported.
 #
 # This file is read by webkitpy/w3c/directory_owners_extractor.py to decide who
 # to contact for new failures; it will read entries with the following format:
 # When removing blacklist entries:
 # * Comment out the line rather than deleting it, to show it is intentional.
 # * Change [ Skip ] to [ Pass ]
 # * Add a leading comment: ## Owners: user@example.com
 #
 # We may want to move towards importing but not running directories without
 # owners, in order to make it easier to enable or run them in the future --
 # directories that are imported but not run are listed in NeverFixTests.
