This is part of a larger project in cleaning up core's admin CSS. This collapses all colors used in the CSS to one of 12 blues, greens, reds, and yellows, 13 grays, pure black, and pure white. The colors are perceptually uniform from light to dark, half of each range has a 4.5 or higher contrast against white, the other half has a 4.5 or higher contrast against black.
Standardizing on this set of colors will help contributors make consistent, accessible design decisions. The full color palette can be seen here: https://codepen.io/ryelle/full/WNGVEjw

This allows a menu item `post_date` to be set to particular value, rather than only allowing it to be set to "now". In particular, the WordPress Importer can use this to perform faster, more accurate duplicate checks.

`wp_insert_post()` has a few checks using `post_date` and `post_date_gmt`, to determine the correct post date. This functionality is now extracted out into a new `wp_resolve_post_date()` function, allowing the checks to be reused elsewhere.

Since WordPress 2.5 and 2.6, `post_content` and `post_excerpt` have both had export-specific filters: `the_content_export`, and `the_excerpt_export`, respectively. `post_title`, however, has used `the_title_rss`, which behaves differently in two important ways:
- It strips HTML tags from the string.
- It HTML-encodes the title string.
These behaviours are not ideal for exports, since it changes the post title, resulting in data loss in export files, and incorrect post duplicate matching on import. This changes replaces the usage of `the_title_rss` with a new filter, `the_title_export`. The new filter is intended to be used in the same as `the_content_export` and `the_excerpt_export`.

Previously, the `enum` keyword was validated by perform a strict equality check. For `string` types this is generally ok, but it prevented using alternative types like `number` when rich type support isn't available.
Now the same level of type coercion/sanitization is applied when validating `enum` as all other validation checks. This means that a value of `"1"` will be accepted for an `enum` of `[ 0, 1 ]`. Additionally, `object` types now properly ignore key order when checking for equality.

In [49752] a check was added to prevent creating new Application Passwords if Basic Auth credentials were detected to prevent conflicts. This check takes place in WP-Admin, though a conflict would only arise if Basic Auth was used on the website's front-end.
This commit extracts the Basic Auth check into a reusable function, `wp_is_site_protected_by_basic_auth()`, which can be adjusted using a filter of the same name. This way, a site that uses Basic Auth to protect WP-Admin can still use the Application Passwords feature.
In the future, instead of requiring the use of a filter, WordPress could make a loopback request and check for a `WWW-Authenticate` header to make this detection more robust out of the box.

To be able to disable jQuery Migrate as step 3 of updating the jQuery version shipped with WordPress, all `JQMIGRATE` warnings in the browser console will have to be addressed.
This includes many minor adjustments to a wide array of core files.
Follow-up to:
* Step 1: Disabling jQuery Migrate 1.4.1 in WordPress 5.5: [48323], [48324]
* Step 2: Updating jQuery to 3.5.1 and adding jQuery Migrate 3.3.x in WordPress 5.6: [49101], [49338], [49615], [49649]

This changeset introduces a filter-based Robots API, providing central control over the `robots` meta tag.
* Introduces `wp_robots()` function which should be called anywhere a `robots` meta tag should be included.
* Introduces `wp_robots` filter which allows adding or modifying directives for the `robots` meta tag. The `wp_robots()` function is entirely filter-based, i.e. if no filter is added to `wp_robots`, no directives will be present, and therefore the entire `robots` meta tag will be omitted.
* Introduces the following `wp_robots` filter functions which replace similar existing functions that were manually rendering a `robots` meta tag:
* `wp_robots_noindex()` replaces `noindex()`, which has been deprecated.
* `wp_robots_no_robots()` replaces `wp_no_robots()`, which has been deprecated.
* `wp_robots_sensitive_page()` replaces `wp_sensitive_page_meta()`, which has been deprecated. Its rendering of the `referrer` meta tag has been moved to another new function `wp_strict_cross_origin_referrer()`.
Migration to the new functions is straightforward. For example, a call to `add_action( 'wp_head', 'wp_no_robots' )` should be replaced with `add_filter( 'wp_robots', 'wp_robots_no_robots' )`.
Plugins and themes that render their own `robots` meta tags are encouraged to switch to rely on the `wp_robots` filter in order to use the central management layer now provided by WordPress core.

This change restructures the Button element styles for better a11y and expected color behaviors. Here what has changed:
- The `button-style()` mixin is now the ''single source or truth'' for how Button should look site-wide.
- Button Block, File Block, and Search form Blocks all rely on this one mixin.
- The same styles is also applied to the `<button>` element which appears in widgets, the 404 search form and comments form.
- Improves expected button styles for various conditions and contexts as follows:
- User color palette selections for Buttons are retained regardless of a parent block’s color settings or dark-mode.
- Supports both Default/Filled styles and Outline styles.
- More consistent `:hover` and `:active` styles.
- `:focus` styles are now always visible and legible.
- Adds a `--local-color` color variable to scope color relationships to nested blocks.
- Reduces selectors in `style.css` output.
- 1:1 experience between editor and front end button styles.
- Properly supports Dark-mode.
