feat: Add Query, Header and Cookie attributes for direct Controller injection

[patel-vansh]

Description
This PR introduces attribute-driven parameter resolution for controller methods, allowing HTTP request data to be injected directly into method parameters using PHP 8 attributes.

It enhances CodeIgniter’s controller parameter resolution system while preserving existing routing, form request, and default parameter behaviors.

Controller method parameters can now be annotated with request-source attributes:

• #[Query] → Inject query string values
• #[Header] → Inject HTTP header values
• #[Cookie] → Inject cookie values

Example

class MyController {
    public function index(
        int $id,
        #[Query('limit')] int $limit = 10,
        #[Header('X-Tenant-Id')] string $tenantId
    ) {
        // $limit and $tenant will be fetched from Query and Header respectively.
        // Passing of parameters to attribute is optional, if no $key is passed to attribute, it'll default to name of the parameter itself
    }
}

Currently, its a draft PR for others to see implementation. I haven't added tests or updated userguide yet.
