A multi-type schema is a schema where the `type` keyword is an array of possible types instead of a single type. For instance, `[ 'object', 'string' ]` would allow objects or string values.
In [46249] basic support for these schemas was introduced. The validator would loop over each schema type trying to find a version that matched. This worked for valid values, but for invalid values it provided unhelpful error messages. The sanitizer also had its utility restricted.
In this commit, the validators and sanitizers will first determine the best type of the passed value and then apply the schema with that set type. In the case that a value could match multiple types, the schema of the first matching type will be used.
To maintain backward compatibility, if unsupported schema types are used, the value will always pass validation. A doing it wrong notice is issued in this case.
Fixes#50300.

This allows for using multi-type support with a string that has a format. For backwards compatibility support, the format validation will still apply if the type is not specified, or it is invalid.
Two new doing it wrong notices are issued when omitting a type, or using an invalid type.

These endpoints facilitate the Block Directory Inserter feature in Gutenberg. Users can now install, activate, deactivate, and delete plugins over the REST API. The block directoryendpoint allows searching for available blocks from the WordPress.org block directory.

Currently themes can declare support for a given feature by using add_theme_support(). This commit adds a register_theme_feature() API that allows plugins and WordPress Core to declare a list of available features that themes can support.
The REST API uses this to expose a theme's supported features if the feature has been registered with "show_in_rest" set to true.

Previously, the WP_REST_Request object validated that top-level properties were defined, but this did not extend to those object's required properties. This adds validation to rest_validate_value_from_schema() directly.
Both the v3 and v4 JSON Schema syntax for required properties is supported.

Previously the _embed flag would embed all embeddable links in a response even if only a subset of the links were necessary. Now, a list of link relations can be passed in the _embed parameter to restrict the list of embedded objects.

The "json" scheme is a holdover from the pre-merge plugin version of the REST API, and was corrected elsewhere in core in [34300]. Only "rest" is officially supported in `set_url_scheme()`.

* 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!
