MR 2 of 2 for Change BlobButtonGroup into a dropdown (#508309 (closed))

move Lock, Replace and Delete buttons
change the dropdown to use GlDisclosureDropdownGroup
I'm temporarily disabling controls for scenarios where we offered a notification to fork a project in order to Replace or Delete a file. See this comment on why the fork suggestion component should change as well. We're behind a feature flag, so I can still tackle that in another MR, before the flag is defaulted.
