Makes the behavior of the filter lines up with its documentation.
Previously, both `$iptc` and `$exif` could return `false` when `exif_read_data()` or `iptcparse()` failed.
Now, if those functions do not return an array, the results are explicitly set to `array()`.

Return the correct file path from `wp_crop_image()` when a developer modifies the file type with via the `image_editor_output_format` filter.
Previously the function would return a broken file reference containing the original file extension rather than the one specified via the filter.

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.

For certain images, `wp_exif_frac2dec()` unexpectedly returned a string instead of `int` or `float`. This can occur when an image is missing meta and calls the function with `'0/0'`. For those images, a fatal error was thrown on PHP 8.0+:
{{{
TypeError: round(): Argument #1 ($num) must be of type int|float, string given
}}}
Upon deeper review, inconsistent and unexpected results were returned from different types of input values passed to the function.
Changes are:
* Maintains backwards-compatibility for valid input values.
* Fixes handling of invalid input values by bailing out to return the documented type of `int|float` by returning `0`.
* Improves the fractional conditional check.
* Improves the calculated fraction handling to ensure (a) the numerator and denominator are both numeric and (b) the denominator is not equal to zero.
* Safeguards the behavior via tests for all possible ways code could flow through the function.
* Safeguards the backwards-compatibility of the `wp_read_image_metadata()` by adding some defensive coding around the calls to the `wp_exif_frac2dec()` function.
These changes fix the fatal error and make the function more secure, stable, and predictable while maintaining backwards-compatibility for valid input values.

This matches the documentation for the filter of the same name.
Previously, the function could return `false` for an audio or video attachment that does not exist in the local filesystem.

Add support for uploading, editing and saving WebP images when supported by the server.
Add 'image/webp' to supported mime types. Correctly identify WebP images and sizes even when PHP doesn't support WebP. Resize uploaded WebP files (when supported) and use for front end markup.

Previously, we used `DIR_TESTDATA` to determine if a test should skip a newly silenced error in `wp_getimagesize()`.

Previously, all logic utilizing `getimagesize()` was supressing errors making it difficult to debug usage of the function.
A new `wp_getimagesize()` function has been added to allow the errors to no longer be suppressed when `WP_DEBUG` is enabled.

In PHP 8, the GD extension uses `GdImage` objects instead of resources for its underlying data structures.
This updates the existing `is_resource()` calls for image resources in core to accomodate for `GdImage` instances as well.

- Run the `wp_generate_attachment_metadata` filter at the end in `wp_update_image_subsizes()` when new metadata was generated and additional image sub-sizes were created.
- Add another arg in the `wp_generate_attachment_metadata` filter for additional context.
- Fix inline docs and ensure the new image meta is always saved before starting post-processing.
