WIP: Move 'Upgrade-Insecure-Requests' to the browser process.

third_party/WebKit/LayoutTests/W3CImportExpectations

 # This file controls which subdirectories of the w3c test repos we do (or don't) 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; to allow it to read
 # When removing blacklist entries:
 # * Comment out the line rather than deleting it, to show it is intentional
 # * Change [ Skip ] to [ 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

 # wpt.config.json overrides the following files with LayoutTests/resources
 # files. Having unused files would be confusing.
