[FEATURE]: Option to create dynamic tables

### Feature hasn't been suggested before.

- [x] I have verified this feature I'm about to request hasn't been suggested before.

### Describe the enhancement you want to request

It would be great to have an option to manage tables in the database at runtime, not just through migrations.

For example:
```ts
const tableFactory = (name: string) =>
sqliteTable(name, {
id: integer({ mode: "number" }).primaryKey({ autoIncrement: true }),
....other columns
});

await tableFactory("some_table").createIfNotExists()
```

Or at least an option to generate SQL from this:
```ts
const tableFactory = (name: string) =>
sqliteTable(name, {
id: integer({ mode: "number" }).primaryKey({ autoIncrement: true }),
....other columns
});

const sql = tableFactory("some_table").getSQL()

await db.$client.execute(sql);
```

Start by tracing the sqliteTable factory and the database $client.execute path mentioned in the examples. Determine whether runtime table creation or SQL generation is the intended scope, then define how dynamic table names and columns should be represented. Done means one supported API works at runtime with appropriate verification for the generated or executed table definition.
