Implement change_table_comment and change_column_comment

Use `TOPLEVEL_BINDING` in rails runner command

Binding to capture the local scope. This means that if a constant with same
name as constant specified by the user exists in local scope, constant
defined in local will use. This is different from what the user expects.
Therefore, fixed to use top-level binding instead of local scope.
