In WordPress 3.2 support for IE6 was dropped, IE7 followed a few versions later. With the 4.8 release, WordPress officially ended support for Internet Explorer versions 8, 9, and 10. Yet, we still have shipped CSS for the unsupported IE versions....until now! Goodbye to ie.css and star hacks!
* Removes ie.css and `ie` style handle.
* Removes IE specific class names and any related CSS.
* Drops support for IE8 and older in `wp_customize_support_script()`.
* Updates compatibility mode for CSS minification to `ie11`.

The use case this helps the most is when there's only one menu and you click "create a new menu". In this case the Cancel link allows you to go back to the single existing menu.

Previously, the method was called with two parameters in `::do_items()`, while the method signature only included one parameter.
Technically, this was not an issue as `WP_Dependencies::do_item()` is a placeholder meant to be overwritten when extending the class. When handling scripts, `WP_Dependencies` is extended with `WP_Scripts`, and the `$group` parameter was only used in `WP_Scripts::do_item()`, which does expect a second argument.
However, officially adding the parameter to `WP_Dependencies::do_item()` signature prevents code misunderstanding and avoids a warning in PHP code inspection tools.

Triggering the error handler during updates may cause false positives. For example, updates may temporarily "fail" while files are moved around, but work fine once completed. Sending emails about temporary failures would just be confusing to the recipient.

This ensures that if the limit has been modified for admin screens by `wp_raise_memory_limit()`, the original value is displayed along with the current value.

This avoids displaying duplicate content of the home page under different URLs with appended page numbers.
This change only affects the `<!--nextpage-->` pagination (`page` query variable) and not the regular multiple posts pagination (`paged` query variable).
The posts page does not support the `<!--nextpage-->` pagination, so requests for invalid page numbers should be redirected to the page permalink, applying the logic previously implemented for single posts or pages.

The array returned by this function previously included a fourth element only when an intermediate image size was used. This change ensures a consistent structure in the returned array regardless of the function's internal behaviour.

As part of the continued effort to improve PHP compatibility, the following improvments are being made:
- Removing deprecated PHP `safe_mode` checks not found in bundled external libraries.
- Change the remaining `while` loops using `each()` to `foreach` loops.
- Prevent false positives from being flagged for the `sodium_compat` library being caused by loading this in a non-standard way.
- Add inline comments to not flag deprecated PHP directives in the getID3 library.

This avoids displaying duplicate content of the same post under different URLs and ensures the canonical URL is correct.
Previously, requests for invalid page numbers were only redirected to the post permalink if the post was actually paginated using the `<!--nextpage-->` marker.
