This currently works for files but the implementation will be harder for folders. Attached screenshots of the 4 current use cases:

1. File in Google Drive - 'Manage with Drive' opens the doc in Google Drive, 'Share with Others' opens the sharing dialog.
2. Folder in Google Drive - 'Manage with Drive' is greyed out for now, 'Share with Others' opens the sharing dialog.
3. File in Team Drives - 'Manage with Drive' opens the doc in Google Drive, 'Share with Others' also opens the doc in Google Drive.
4. Folder in Team Drives - 'Manage with Drive' and 'Share with Others' are both greyed out.

Waiting to speak with the Drive API team on the best way to get a link to open a folder in Google Drive using the sync API.

Add 'Manage in Drive' button to Files App context menu

Adds a 'Manage in Drive' button to the context menu for entries in the
Files app for ChromeOS.

Creates a new DriveManageAction which appears enabled only for
non-directory entries (for now) in Drive when offline mode is not
enabled. Uses getEntryProperties() for the entry to get its
'alternateUrl' (provided by the Drive Sync API) and navigates to this
URL in the browser.

'Manage in Drive', ensure the browser window opens and navigates to the
file.

Test: Right-click on a file in Google Drive in the File Manager, select

Move |alternate_url| to ResourceEntry in drive.proto

Move |alternate_url| to ResourceEntry in drive.proto. Previously, it was
in FileSpecificInfo, so this patch upgrades it to be set for directories
also.

This is pre-work to allow the 'Manage in Drive' button to work for
folders in the Files app, as well as files.

Enable 'Manage in Drive' button for directories in the Files app

Enable the 'Manage in Drive' button for directories, as well as files,
and update the relevant tests. It was previously disabled because
|alternate_url| was not available for directories.
