* PHP 8.1: fix deprecation warnings / http_build_query()
This fixes all relevant calls to the PHP native `http_build_query()` function.
The second parameter of which is the _optional_ `$numeric_prefix` parameter which expects a `string`.
A parameter being optional, however, does not automatically make it nullable.
As of PHP 8.1, passing `null` to a non-nullable PHP native function will generate a deprecation notice.
In this case, these function calls yielded a `http_build_query(): Passing null to parameter #2 ($numeric_prefix) of type string is deprecated` notice.
Changing the `null` to an empty string fixes this without BC-break.
Fixes a few deprecation warnings found when running the tests.

* PHP 8.1: fix deprecation notices / PharData::__construct()
This fixes all relevant calls to the PHP native `PharData::__construct()` method.
The second parameter of this method is the _optional_ `$flags` parameter which expects an `int` of flags to be passed to the `Phar` parent class `RecursiveDirectoryIterator`.
Fixed by passing the default value for the `$flags` parameter as per the `RecursiveDirectoryIterator::__construct()` method.
The third parameter of the method is the _optional_ `$alias` parameter which expects an `string`.
Fixed by passing an empty string.
Fixes various notices along the lines of:

This adds support for Xdebug3 modes and changes the default behaviour
from always restarting if Xdebug is loaded, to only restarting if Xdebug
is active.
Xdebug is considered active if it is loaded, and for Xdebug3, if it is
running in a mode other than `xdebug.mode=off`.

PHP 8.1 supports Enums, and [Enums follow class-semantics](https://php.watch/versions/8.1/enums#class-semantics-autoload).
Composer's class-map generator currently looks for `class`, `interface`, and `trait` keywords. If Composer is run in PHP 8.1 or later, Composer now additionally looks for `enum` keyword as well. This is similar to how Hack's `enum` support is added.
This PR also adds tests for basic enums, backed enums, namespaced enums, and an enum that implements an interface and extends a class.
