Update the wp_add_inline_script function to provide a means for specifying an inline script as being standalone

[10upsimon]

Description

As part of enhancing the Scripts API with a loading strategy, there is a requirement to correctly handle inline scripts attached to main scripts so that their execution order is maintained. Inline scripts may, however, want to remain totally strategy agnostic and function in a standalone mode, having no inherent need to obey any parent/main script loading strategies. In order to provide this functionality, inline scripts should be able to specify/opt in to a standalone mode.

The existing wp_add_inline_script method, currently residing in WordPress core source at this location, should therefore be updated to cater for this new requirement. It should achieve this by way of introducing a new $standalone parameter to the function. This boolean parameter will be used to determine whether a user has opted for said inline script to be $standalone or not.

Acceptance Criteria

• Enhancement to the existing wp_add_inline_script method, allowing the specification of a boolean value against a new $standalone parameter. This method currently resides in WordPress core source at this location.
  • Addition of a new $standalone parameter to said above function.
  • The $standalone parameter is to be of type boolean
  • The $standalone parameter is to have a default value of false

Unit Tests

• Unit tests for the various processes surrounding wp_add_inline_script method currently reside in WordPress core source, starting at this location.
• Applicable tests should be added that assert that the values of $standalone are of type boolean.
• Applicable tests should be added that assert that the default value of $standalone is false.

@10upsimon I notice this one is in To Do, but there's no comments relating to AC approval? Is it correct that it is ready to be worked on?
