feat(database): use different text type declaration with mysql according to field length

[MrYamous]

Fixes #1941

While working on it, I realized this may can be applied to Integer too

I like that you can just specify a number here, and it will determine the correct type for you. However, I think I'd rather see it a bit more flexible:

1. instead of constants on MySQLConfig, let's refactor to an enum (not sure about the name yet)

enum TextLength: int
{
    case TINY = 255;
    case DEFAULT = 65535;
    case MEDIUM = 16777215;
    case LONG = 4294967295;
}

2. Then users could provide either an int or this enum: int|TextLength|null $length = null
3. We could make the field non-optional for clarity: int|TextLength $length = TextLength::TEXT
4. Improve the enum so that all logic is contained in one place:

enum TextLength: int
{
    case TINY = 255;
    case DEFAULT = 65535;
    case MEDIUM = 16777215;
    case LONG = 4294967295;

    public static function fromLength(int $length): self
    {
        return match (true) {
            $length > TextLength::LONG => TextLength::LONG,
            $length > TextLength::MEDIUM => TextLength::MEDIUM,
            $length > TextLength::DEFAULT => TextLength::DEFAULT,
            default => TextLength::TINY,
        };
    }

    public function toString(): string
    {
        return match($this) {
            TextLength::TINY => 'TINYTEXT',
            TextLength::DEFAULT => 'TEXT',
            TextLength::MEDIUM => 'MEDIUMTEXT',
            TextLength::LONG => 'LONGTEXT',
        };
    }
}

WDYT?

I'm only a bit concerned about names, because as far as I understand, this is only necessary for MySQL — right?

In SQLite, the limit of TEXT can be set in SQlite config, standard are 1 GB (1.000.000.000 Bytes): https://sqlite.org/limits.html

In PostgreSQL TEXT is without limit. https://www.postgresql.org/docs/current/datatype-character.html

From your three supported database types, only MySQL has TINYTEXT, TEXT, MEDIUMTEXT, LONGTEXT. https://dev.mysql.com/doc/refman/8.4/en/blob.html

MySQL is some times little bit frustating with this.

I see your point and looks good to me, it's probably more friendly to use if we allow an Enum here.
But I think TextLength is too generic, WDYT about DatabaseTextLength, FieldTextLength or MySQLTextLength ?
