This change fixes oEmbed host script enqueueing on front-end when using block themes.
It deprecates `wp_oembed_add_host_js` in favor of `wp_maybe_enqueue_oembed_host_js`. The action is still triggered in `default-filters.php` to ensure backward compatibility for websites that are removing the action. There is now a `has_action()` check in `wp_maybe_enqueue_oembed_host_js()` to see if `wp_oembed_add_host_js()` has not been unhooked from running at the `wp_head` action.
Follow-up to [52132], [52151], [52153], [52325].

Due to the way that the `blockquote` and `iframe` are being parsed with a regular expression in `wp_filter_oembed_result()`, if there is any content at all before the `blockquote` start tag then it will fail to be included in the first matching group. By appending the `wp-embed` script instead of prepending it in `get_post_embed_html()`, then the parsing issue is avoided.
Also use non-greedy match `wp_maybe_enqueue_oembed_host_js()`.
Amends [52132].

* Prevent loading `wp-embed` script unconditionally on every page in favor of conditionally enqueueing when a post embed is detected. The `wp-embed` script is also explicitly marked as being in the footer group. Sites which currently disable post embed scripts from being enqueued via `remove_action( 'wp_head', 'wp_oembed_add_host_js' )` will continue to do so.
* Send a `ready` message from the host page to each post embed window in case the `iframe` loads before the `wp-embed` script does. When the `ready` message is received by the post embed window, it sends the same `height` message as it sends when it loads.
* Eliminate use of `grunt-include` to inject emoji script and the post embed script. Instead obtain the script contents via `file_get_contents()` (as is done elsewhere in core) and utilize `wp_print_inline_script_tag()`/`wp_get_inline_script_tag()` to construct out the script. This simplifies the logic and allows the running of src without `SCRIPT_DEBUG` enabled.
* For the embed code that users are provided to copy for embedding outside of WP, add the `secret` on the `blockquote` and `iframe`. This ensures the `blockquote` will be hidden when the `iframe` loads. The embed code in question is accessed here via `get_post_embed_html()`.

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 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.

Using the canonical function name for PHP functions is strongly recommended, as aliases may be deprecated or removed without (much) warning.
This replaces all uses of the following:
* `join()` with `implode()`
* `sizeof()` with `count()`
* `is_writeable()` with `is_writable()`
* `doubleval()` with a `(float)` cast

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.

* 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!

Screen reader users rely on the iframe title attribute to describe the contents of iframes. A meaningful title attribute allows to quickly identify the iframe content, so users can determine which iframe to enter and explore in detail or skip if desired.
Note: this is the only case where a title attribute is required for compliance with the W3C Web Content Accessibility Guidelines (WCAG).
- checks for oEmbed response of type `video` or `rich`
- checks if they use an iframe
- fetches the title (if any) from the oEmbed response

After the JavaScript reorganization in [43309], it was no longer possible to test WordPress from the `src` folder. That meant a build step was required to test PHP modifications. That is suboptimal as even a simple copy is slower than a web server just serving the new file.
We achieve building to `src` by setting a `WORKING_DIR` constant in the Gruntfile that is `build` by default, but changes to `src` when the `--dev` flag is present on any Grunt command. We provide sensible defaults so some commands, such as copying `version.php`, always build to `build`.
Because testing from `build` is no longer required, we change the messages present in `index.php` and `wp-admin/index.php` to be more broadly about building WordPress.
We also change the webpack config to have more straightforward behavior based on the `buildTarget` argument. It only determines the build target now and has no implicit behavior anymore. `grunt build` still works as it worked before, to make sure that the build server produces the same `wordpress.zip` we are used to.
We do all this instead of a symlink setup because symlinks don't work on every platform.
