[core] Migrate shredding map on rename and drop commands

[ArnavBalyan]

Purpose

• Rename and drop on map column fails with :Field can not be found in table schema.
• This is because the column specific map shredded keys are not migrated in renames and drops.
• Add the map.* keys to the rename option migration whitelist and strip them on drop, so rename/drop of a shredding map column succeeds and keeps its layout options.

Tests

• UT
