Add COMPONENT to worker-dev OWNERS files for tests

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 ]

 # external/wpt/workers [ Pass ]
 
 # Exceptions for individual files that fail due to bugs in the
 # upstream tests that we shouldn't bother importing until they are
 # fixed. Please include an explanation, ideally with a crbug reference
 # (if it's a blink/test tooling issue) or an upstream bug reference
 # (if the test itself is buggy).
 
 # wpt.config.json overrides the following files with LayoutTests/resources
 # files. Having unused files would be confusing.
