16b8d91baa I18N: Improve translator comments.
* 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!

05fa2363ab Posts: Avoid the use of globals in get_the_content() and related functions.
This changeset introduces `$post` parameters to `get_the_content()` and
`wp_trim_excerpt()`. When a `$post` object is passed to one of these functions,
the functions will operate on the data from that object, rather than from the
post globals (`$authordata`, `$page`, etc). This ensures that the functions work
in a predictable manner when used outside of the regular post loop.

The global-mismatch problem is surfaced in cases where `get_the_excerpt()` is
called outside of the post loop, on posts that don't have a defined excerpt. In
these cases, the post globals - used to generate a fallback excerpt - may refer
to the incorrect object, resulting in PHP notices or other unpredictable
behavior. See #36934 for a related issue.

c339798b49 Themes: Introduce responsive embeds support.
Responsive embeds is a way for a theme to opt in to WordPress dynamically scaling the width/height of an embed. When a theme supports responsive embeds, a `wp-embed-responsive` class is added to the `<body>` tag. This information is also presented through the REST API for clients to respect.

81a26f6900 Posts, Post Types: Add support for post type templates.
WordPress has supported custom page templates for over 12 years, allowing developers to create various layouts for specific pages.
While this feature is very helpful, it has always been limited to the 'page' post type and not was not available to other post types.

By opening up the page template functionality to all post types, we continue to improve the template hierarchy's flexibility.

In addition to the `Template Name` file header, the post types supported by a template can be specified using `Template Post Type: post, foo, bar`.
When at least one template exists for a post type, the 'Post Attributes' meta box will be displayed in the back end, without the need to add post type support for `'page-attributes'`. 'Post Attributes' can be customized per post type using the `'attributes'` label when registering a post type.

d31057a009 Posts: Add filter to allow overriding post_password_required return
Post Passwords are incredibly inflexible. One Password per site at a time and other limitations that can't really be changed without a backwards compatibility break.  This adds the ability for sites to change the password behavior such as doing per post passwords or allowing multiple passwords to be set in a browser. The possibilities are YUGE.

Additionally, it allows for a behavior other than returning a html form when a password is needed. This is important for non website use cases (such as in a restful API).

Fixes #38056. See #16483.
Props rmccue.

4131900722 Menus: Add white space option to wp_nav_menu() and wp_list_pages().
Adds an `item_spacing` option to the arguments array for the functions `wp_nav_menu()`, `wp_list_pages()`, and `wp_page_menu()`. `item_spacing` is a boolean accepting either `preserve` or `discard`.

Previously, certain CSS choices could result in a site's layout changing if `wp_nav_menu()` fell back to the default `wp_list_pages()` due to differences in the whitespace within the HTML. The new argument ensures a function outputs consistant HTML while maintaining backward compatibility.

Fixes #35206.
