Laravel 11: Remove Doctrine DBAL

[hafezdivandari]

Description

Doctrine DBAL has been removed from Laravel 11.x:

• laravel/framework#48864
• Laravel 11.x Upgrade Guide

This PR removes doctrine/dbal from filament and uses following Laravel's native schema methods, that are stable since Laravel 10.38, instead:

• Schema::getColumns($table)
• Schema::getColumnListing($table)
• Schema::getIndexes($table)

PS 1: It's my first time contributing to filament, please let me know if I've missed anything, and sorry about that! PS 2: This PR targets laravel-11 branch (#10972), please let me know if you prefer anything else. PS 3: I tried to keep the changes as minimum as possible, but this PR changes the methods' signatures on packages/support/src/Commands/Concerns/CanReadModelSchemas.php, IDK if you consider this as a breaking change or not.
