Add basic Files App display test for offline Drive

Offline Drive has no test coverage, let's add some.

Start Files App with offline Drive and render test files. Verify that
the files are correctly rendered for the 'offline' Drive state.

 file: hello.txt should be rendered as not available offline (dimmed)
 folder: photos  should be rendered as available offline
 pinned: pinned  should be rendered as available offline

Enabled for DriveFS only, per CL:1189515.

Test: browser_test --gtest_filter="*fileDisplayDriveOffline*"

Files App display test for offline Drive should check CSS style

Querying file list elements with .dim-offline class collects the files
that could be rendered with 'offline' style: it does not mean they are
rendered with 'offline' style.

Fix that by requesting .dim-offline elements and their CSS opacity and
checking the opacity has is the expected value for an offline rendered
file list row entry (opacity 0.4 currently).

Files App display test: add online file CSS style tests

When Drive is offline, files that are 'available offline' are rendered
with 'online' CSS style. Verify that those files have the expected CSS
'online' style (opacity 1).

Also add a new Drive 'online' test case to check that all files render
with the CSS 'online' style (opacity 1).

File Display test: check the default path too

Check the default |path| by providing it and call checkIfNoErrors() in
its own step (like every one else).
