In `WP_Image_Editor_Imagick`, bail early in `make_subsize()` if the image is already the requested size. Previously, `make_subsize()` would create another copy of the file. `WP_Image_Editor_GD` doesn't have the same problem.

The existing filter `image_editor_output_format` receives an additional parameter `$size_name` which is populated whenever it controls the output format for a specific registered image size to create. Otherwise, it remains empty. In order to achieve this, a low level change has been added in bringing a new `$size_name` class property to the `WP_Image_Editor` base class, which is introduced in a backward compatible way that will not cause conflicts with custom implementations.
This parameter is then used in new logic inside the `wp_default_image_output_mapping()` callback function for the filter, controlling whether `image/jpeg` should map to `image/webp` output or not. By default, this is enabled for all WordPress core image sizes by default, and this list can be modified using a new `wp_image_sizes_with_additional_mime_type_support` filter, e.g. to remove core sizes or add custom sizes.
The customization per image size may be further enhanced by providing a more declarative API via a new parameter on the `add_image_size()` function.

Store the file size of all newly uploaded attachments, as part of the metadata stored in post meta. Storing file size means, developers will not have to resort to doing `filesize` function calls, that can be time consuming on assets on offloaded to services like Amazon’s S3.
This change also introduces a new helper function called, `wp_filesize`. This is a wrapper around the `filesize` php function, that adds some helpful filters and ensures the return value is an integer.

Renames the first parameter in `WP_Image_Editor_GD::save()` to match the parent's method signature.
Why? PHP 8 introduces the ability to pass named arguments to function/method calls. This means the child and parent method signatures (i.e. parameter names) need to match.
Adds @since to clearly specify why the change happened.
Adds parameter descriptions to parent and both child classes.

Since `WP_Image_Editor`'s introduction, stream wrappers have functioned in `WP_Image_Editor_GD`, but haven't been properly supported in `WP_Image_Editor_Imagick`.
- Detects stream wrappers and uses `file_put_contents()` along with `Imagick::read/getImageBlob()` for handling when necessary.
- Introduces private method, `WP_Image_Editor_Imagick::write_image` to handle detection and proper saving.
- Introduces `WP_Test_Stream` class for testing stream wrappers, along with new tests for Imagick's stream handling and a stream filename test.
Adds requirement for `Imagick::readImageBlob()`, available in Imagick >= 2.0.0, which aligns with the current requirement of Imagick >= 2.2.0.

“The WordPress open source community cares about diversity. We strive to maintain a welcoming environment where everyone can feel included.”
With this commit, all occurrences of “whitelist” and “blacklist” (with the single exception of the `$new_whitelist_options` global variable) are removed. A new ticket has been opened to explore renaming the `$new_whitelist_options` variable (#50434).
Changing to more specific names or rewording sentences containing these terms not only makes the code more inclusive, but also helps provide clarity. These terms are often ambiguous. What is being blocked or allowed is not always immediately clear. This can make it more difficult for non-native English speakers to read through the codebase.
Words matter. If one contributor feels more welcome because these terms are removed, this was worth the effort.

Hook documentation should be on the line directly above the line containing the `do_action()` or `apply_filters()` call.

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.

Prior to about 2013, many class methods lacked even access modifiers which made the `@access` notations that much more useful. Now that we've gotten to a point where the codebase is more mature from a maintenance perspective and we can finally remove these notations. Notable exceptions to this change include standalone functions notated as private as well as some classes still considered to represent "private" APIs.
