The `IXR_Message` class declares a property `_currentTag`, which is never assigned or used. It does assign to `currentTag` instead, which outside of that one assignment is never used either.
Since there are various other underscore-prefixed properties declared on the class, including one named `_currentTagContents` which is used in several places, it appears that the declared property is correct and the assignment is a typo.
This commit resolves a notice on PHP 8.2:
{{{
Deprecated: Creation of dynamic property IXR_Message::$currentTag is deprecated
}}}

When the XML-RPC endpoint is enabled, always return a HTTP `200 OK` status code in accordance with the XML-RPC specification. Continue to return an HTTP `405 Method Not Allowed` status code when the endpoint is disabled.

Rather than relying `func_get_args()` to retrieve arbitrary function arguments, we can now use the spread operator to assign them directly to a variable.
This makes the signature of `WP_HTTP_IXR_Client::query()` compatible with the parent class method.

The `$HTTP_RAW_POST_DATA` global was deprecated in PHP 5.6 and removed completely in PHP 7.0. In general, `php://input` should be used instead of `$HTTP_RAW_POST_DATA`.
Because WordPress Core still supports PHP 5.6, some plugins or sites may still rely on this variable being present and populated with the expected data. For that reason, occurrences of the variable will remain with updated inline documentation until support for PHP 5.6 is officially dropped in WordPress.

Use of `date()` in core depends on PHP timezone set to UTC and not changed by third party code (which cannot be guaranteed).
`gmdate()` is functionally equivalent, but is not affected by PHP timezone setting: it's always UTC, which is the exact behavior the core needs.

There are a handful of places where we don't check that the XML functions exist before we use them. Ubuntu's PHP 7 packages don't include PHP-XML by default, increasing the chance of this causing issues.
