[autotest] Add a dummy database migration as a placeholder for the reverted CL
As mentioned in the db migrate comment:
This database migration does nothing. It works as a replacement for a reverted
migrate CL: https://chromium-review.googlesource.com/#/c/253760
For routine database migration revert, a new CL should be added to add
DOWN_SQL of the reverted migration as UP_SQL. However, in that CL's case,
DOWN_SQL is not available.
The dummy migration avoid the requirement to manually downgrade migrate_info
in each database.
BUG=None
TEST=./database/migrate.py sync
