Sergey Biryukov 651f426b3a General: Remove `noreferrer` from `wp_targeted_link_rel()` and other uses.
When `noopener noreferrer` was originally added in #37941 and related tickets, the `noreferrer` bit was specifically included due to Firefox not supporting `noopener` at the time.

Since `noopener` has been supported by all major browsers for a while, it should now be safe to remove the `noreferrer` attribute from core.

Sergey Biryukov 0e3147c40e Coding Standards: Replace alias PHP functions with the canonical names.
Using the canonical function name for PHP functions is strongly recommended, as aliases may be deprecated or removed without (much) warning.

This replaces all uses of the following:
* `join()` with `implode()`
* `sizeof()` with `count()`
* `is_writeable()` with `is_writable()`
* `doubleval()` with a `(float)` cast

In part, this is a follow-up to #47746.

Gary Pendergast abcbee954f Coding Standards: Fix instances of `WordPress.PHP.NoSilencedErrors.Discouraged`.
Noteable changes:
- The `magic_quotes_runtime` and `magic_quotes_sybase` settings were removed in PHP 5.4, so no longer need to be set.
- Some functions that use external libraries can generate errors that can't be tested for, so are globally allowed to silence errors.
- Quite a few functions would cause errors if `safe_mode` was set. This setting was removed in PHP 5.4.
- Only a handful of `header()` calls needed corresponding `headers_sent()` checks for unit tests to pass, but more may need to be added as the nightlies builds are tested.

Sergey Biryukov 2931a2d95e Widgets: Make sure changes to media widgets' instance schema via `widget_{$this->id_base}_instance_schema` filter are not overridden by subclasses.
Previously, `WP_Widget_Media_Audio`, `WP_Widget_Media_Image`, and `WP_Widget_Media_Video` used to override the changes due to reversed arguments in `array_merge()` call.

Andrea Fercia 5c60995bd4 Accessibility: Replace media placeholder clickable divs with buttons.
`<button>` elements are natively interactive, supported by any assistive technology, and must be used instead of non-semantic, non-accessible `<div>` elements.

Also, this change aligns the Media Widgets and the Customizer site icon and site logo controls with the design pattern used in the new Block Editor for similar controls.

Props ramonopoly, welcher, afercia.

Andrea Fercia adc7f9fe54 Accessibility: Improve the image and gallery widgets preview accessibility.
In an authoring context, the image `alt` attribute purpose is different from the one for the front end. For example, screen reader users need to know what the selected image is, even when the original `alt` value is empty.

This change introduces a new pattern for the `alt` text in an authoring context:
- uses the `alt` text if not empty
- when there's no `alt` text, informs users the image has no alternative text and provides a reference to the image filename

Also, makes the gallery media widget preview an unordered list to make screen readers announce the number of images automatically.

Fixes #43137.
