Previously, changing the post thumbnail of a published post in the edit screen
would immediately apply the change, rather than waiting for the post to be
saved before applying the update. This could lead to someone unintentionally
editing the post thumbnail on a published post, and made it impossible to
preview changes to post thumbnails on published posts before saving the change.
This introduces a new Ajax handler, `wp_ajax_get_post_thumbnail_html()` to
retrieve the HTML for the post thumbnail meta box without updating the post
meta value for `_thumbnail_id`. It also allows post thumbnail changes to be
previewed by passing the `_thumbnail_id` as a query variable to the preview
screen and adding a new filter, `_wp_preview_post_thumbnail_filter()`, which
gets applied to `get_post_metadata` during the post preview process.

This is a follow up to [38065] to ensure that `wp.html.string()` always
converts empty `alt` attributes to `alt=""` rather than returning HTML using
empty attribute notation, like `alt`. This allows screen readers to ignore
images with empty `alt` attributes, rather than reading out the URL string.
Additionally this completely removes the logic in `wp.html.string()` for
converting blank attributes to empty attribute notation since empty attribute
notation is generally meant to denote a boolean value, e.g.,
`checked` == `checked="checked"`, which doesn't apply in this context because
boolean attributes must be omitted in order to represent a `false` value.

When `IMAGE_EDIT_OVERWRITE` is set to true, edited image files are
supposed to be deleted when an image is restored to the original.
However, when an image was edited more than once, and then restored,
files created during previous edits were left behind.

leftover images after each edit when `IMAGE_EDIT_OVERWRITE` is true.

Prior to the introduction of `WP_Term_Query`, the 'orderby' clause
passed to the 'terms_clauses' filter was prefixed by `ORDER BY`. After
`WP_Term_Query`, this was not the case; `ORDER BY` was added after the
filter. As such, plugins filtering 'terms_clauses' and returning an
'orderby' clause beginning with `ORDER BY` resulted in invalid syntax
when `WP_Term_Query` prepended a second `ORDER BY` keyword to
the clause.
This changeset rearranges the way the 'orderby' clause is built so that
it will be passed to 'terms_clauses' in the previous format.

Registration is now based solely on object type, which allows the code around this to be simplified significantly.
In the process of making this adjustment:
* `register_meta()`, `unregister_meta_key()`, `get_registered_metadata()`, and `registered_meta_key_exists()` no longer return `WP_Error` objects.
* The recently introduced `wp_object_type_exists()` function and the restriction on object type has been removed.
Note: No guarantee of uniqueness is made across object subtypes. Registered meta keys should be uniquely prefixed to avoid conflict.

When `$size` is passed to `image_get_intermediate_size()` as an array of width
and height values and an exact image size matching those values isn't available,
the function loops through the available attachment sizes and returns the
smallest image larger than the requested dimensions with the same aspect ratio.
The aspect ratio check is skipped for the 'thumbnail' size to provide a fallback
for small sizes when no other image option is available. This resulted in a poor
selection when the size requested was smaller than the 'thumbnail' dimensions
but a larger size matching the requested ratio existed.
This refactors the internals of `image_get_intermediate_size()` to ensure the
'thumbnail' size is only returned as a fallback to small sizes once all other
options have been considered, and makes the control flow easier to follow.
This also introduces a new helper function, `wp_image_matches_ratio()` for
testing whether the aspect ratios of two sets of dimensions match. This function
is also now used in `wp_calculate_image_srcset()` during the selection process.

Previously, when inserting an image from a URL, leaving the `alt`
field blank in the media modal would result in an image being
inserted into the editor without an `alt` attribute, rather than
an empty `alt`. This happened because the `props.type` would not
get set in `wp.media.string.props()` — because `attachment` is
undefined in this case — causing the image fallbacks to get
skipped.
This fixes the issue by explicitly setting `props.type` to 'image'
in `wp.media.string.image()` before filling out the rest of the
properties.

`addReplyTo()` method fixes the issue.

* Set `WP_MEMORY_LIMIT` and `WP_MAX_MEMORY_LIMIT` to current limit if the `memory_limit` setting can't be changed at runtime.
* Use `wp_convert_hr_to_bytes()` when parsing the value of the `memory_limit` setting because it can be a shorthand or an integer value.
* Introduce `wp_raise_memory_limit( $context )` to raise the PHP memory limit for memory intensive processes. This DRYs up some logic and includes the existing `admin_memory_limit` and `image_memory_limit` filters. The function can also be used for custom contexts, the `{$context}_memory_limit` filter allows to customize the limit.
