Per accessibility best practices, it is recommended that all HTML `<img>` elements have an `alt` attribute. Any decorative images should have an empty `alt` attribute (`alt=""`).

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
In part, this is a follow-up to #47746.

Technically, the `$format` argument should always be a string, but passing `false` used to work before [47808], so this restores backward compatibility.
The list of affected functions:
* `get_the_date()`
* `get_the_time()`
* `get_comment_date()`
* `get_comment_time()`

To accommodate for the change, the `custom-logo` theme feature now accepts the `unlink-homepage-logo` parameter.
If and when the logo is linked on the home page, the link has the `aria-current` attribute for better accessibility.

In `get_the_archive_title()` split the internal `$title` variable into `$title` and `$prefix`. By using the new `get_the_archive_title_prefix` filter the prefix can now wrapped with custom elements or removed completely by using
{{{
add_filter( 'get_the_archive_title_prefix', '__return_empty_string' );
}}}
Also, wrap the title part with a `span` element and pass the original title and prefix to the existing `get_the_archive_title` filter, allowing further customization to the archive titles.

After [48039] it became clear that the non-linked custom logo on the home page needs an empty alt attribute, as in most of the cases the logo is decorative and doesn't need its purpose to be described.
This change outputs an empty alt attribute by default for the custom logo on the home page. If necessary, it is possible to use the new 'get_custom_logo_image_attributes' filter to manipulate the default attributes for the logo image and set an alt attribute.

This PR adds a new color scheme option, which uses a high luminosity blue spot color, almost-black menu, and pure white for menu items.
This helps increase contrast, and bring more consistency with some of the higher contrast colors used in the block editor.

Being a good idea in theory, in practice it does not always work reliably, may not recognize newer CSS properties, and sometimes displays phantom errors with no particular error message.
A plugin can re-enable CSS linting via the `wp_code_editor_settings` filter.

The <tfoot> element was allowed to precede the <tbody> element in HTML 5. However, that was changed in HTML 5.1 and <tfoot> must now follow <tbody>.
This removes the tfooot and instead uses a nav element for navigation between months.

This avoids the performance overhead of the function call every time `dirname( __FILE__ )` was used instead of `__DIR__`.
This commit also includes:
* Removing unnecessary parentheses from `include`/`require` statements. These are language constructs, not function calls.
* Replacing `include` statements for several files with `require_once`, for consistency:
* `wp-admin/admin-header.php`
* `wp-admin/admin-footer.php`
* `wp-includes/version.php`
