Add Jakarta Pages (JSP) 4.0 support

[scottmarlow]

WildFly Preview is currently using (Jakarta Pages) jakarta.servlet.jsp-api-3.1.1.jar but should be using jakarta.pages:jakarta.pages-api:jar:4.0.0. I think we need to integrate with a newer version of Jastow that implements https://jakarta.ee/specifications/pages/4.0/

After WildFly Preview is upgraded to Pages 4.0, the following Platform TCK signature test failures should go away:

Failed packages listed below: 
	jakarta.servlet.jsp.tagext(static mode)
	jakarta.servlet.jsp.tagext(reflection mode)
	jakarta.servlet.jsp.el(static mode)
	jakarta.servlet.jsp.el(reflection mode)

^ is a subset of failures just to give an idea of the problem. https://jakarta.ee/specifications/pages/4.0/ describes the Pages 4.0 changes that are needed I think. Below is a description copied from the Pages 4.0 spec page:

Jakarta Pages defines a template engine for web applications that supports mixing of textual content (including HTML and XML) with custom tags, expression language, and embedded Java code, that gets compiled into a Jakarta Servlet.

This release removes deprecated code and provides any additional updates necessary to align with changes in the Jakarta Servlet and/or Expression Language specifications.

New features, enhancements or additions

• Updated ErrorData to add support for the new attributes jakarta.servlet.error.query_string and jakarta.servlet.error.method.

• Removals, deprecations or backwards incompatible changes

• All code deprecated as of Jakarta Server Pages 3.1 has been removed. Specifically:

•    Remove methods that override ELResolver.getFeatureDescriptors() as that method will be removed as of EL 6.0
  

•    Remove the isThreadSafe page directive attribute as the related Servlet API interface SingleThreadModel has been removed as of the Servlet 6.0 specification
  

•    Remove the jsp:plugin action and related actions as the associated HTML elements are no longer supported by any major browser
  

•    Remove JspException.getRootCause()
