[Feature]: support column comment and table comment

[shellphy]

Is your feature request related to a problem? Please describe.

Could you add the ability to comment columns and tables?

Describe the solution you'd like

As laravel's migration provides:

$table->string('avatar')->nullable()->comment('图像');

$table->comment('交易');

Describe alternatives you've considered

Because when viewing a separate view database, if the field is more and more complex, it will be very confusing

This can likely be closed unless wanting to support table comments.

Support for column comments is already integrated: https://github.com/cycle/database/blob/2.x/tests/Database/Functional/Driver/Common/Schema/CommentTest.php
