With this changeset, in addition to the already present `wp_lazy_loading_enabled` filter, developers can now opt out of lazy-loading template images via `wp_get_attachment_image()` by passing a `loading` attribute with boolean value `false`. This can be used e.g. by theme developers on images which are very likely to be in the initial viewport.
This changeset also improves related test coverage.

Following up on [48170], this changeset moves the new logic to add missing `img` dimension attributes into a separate function that is run first within `wp_filter_content_tags()`. It also adds a utility function `wp_image_src_get_dimensions()` with logic reused from `wp_image_add_srcset_and_sizes()`, and it ensures that `width` and `height` attributes only get added if both of the attributes are missing on the original `img` tag.
This changeset furthermore improves test coverage and separates tests for the different aspects of `img` tag modification.

The filter is the callback function added with `add_filter()`, therefore the hook passes a value to the filter, and the filter returns a value to change its behaviour.
The documentation is referring to the latter.

This changeset ensures that attachment images which are inserted without `width` and `height` attributes still receive them in the frontend, to reduce cumulative layout shift. Adding the dimensions happens as part of the logic for adding `srcset` and `sizes` attributes, which already assume the specific width and height of the respective image.
Images are now only lazy-loaded if they have `width` and `height` attributes present. While missing these attributes itself is what causes layout shifts, lazy-loading such images can make this problem more apparent to the user.

Visible `<label>` elements benefit all users. The `placeholder` attribute should not be used as a replacement for visible labels.
Instead, it's supposed to be used only for a short hint to aid users with data entry e.g. a sample value or a brief description of the expected format.
Screen readers may not announce a `placeholder` attribute at all. Other users may suffer from the lack of a visible label and a placeholder used as replacement, for example:
- users with cognitive disabilities may have trouble remembering what the filled field does
- speech recognition users cannot see the name they can speak to set focus on the field
- low-vision users with high text-size may not be able to see the whole placeholder even when it's visible, if its value is clipped by the edge of the input

When a theme declares HTML5 support for script and styles via `add_theme_support( 'html5', array( 'script', 'style' ) )`, the `type="text/javascript"` and `type="text/css"` attributes are omitted.
These attributes are unnecessary in HTML5 and cause warnings in the W3C Markup Validation Service.

* Add missing translator comments.
* Fix placement of some translator comments. Translator comments should be on the line directly above the line containing the translation function call for optimal compatibility with various `.pot` file generation tools. The CS auto-fixing, which changed some inconsistent function calls to multi-line function calls, is part of the reason why this was no longer the case for a select group of translator comments.
Includes minor code layout fixes.
Polyglots, rejoice! All WordPress core files now have translator comments for all strings with placeholders!

Makes sure the media modal dialog `h1` heading isn't empty when custom media frames don't set a title. This is particularly important now that the media modal is an ARIA dialog, as the title is referenced by an `aria-labelledby` attribute to properly label the dialog.

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.

- Introduces `wp_get_missing_image_subsizes()` and `wp_update_image_subsizes()` to generate image sub-sizes that are missing or were not created after the upload.
- Adds a way to display errors that happened while creating sub-sizes.
- Introduces `wp_create_image_subsizes()` intended for use after an image was uploaded. It saves/updates the image metadata immediately after each sub-size is created. This fixes the (long standing) problem when some of the sub-size image files were created but there was a timeout or an error and the metadata was not saved. Until now such uploads were considered "failed" which usually resulted in the user trying to upload the same image again, creating even more "orphan" image files.
Note that the patch also includes some unrelated WPCS fixes.
