[jdk11u-dev] RFR: 8284367: JQuery UI upgrade from 1.12.1 to 1.13.1

[Goetz Lindenmaier]

I backported this from 17.
After replacing script-dir with jquery in the file paths of the patch it
applies somehow. Still, the following adaptions were needed:

src/jdk.javadoc/share/classes/jdk/javadoc/internal/doclets/formats/html/HtmlDoclet.java
Context: jszip files are not in the list in 17.

src/jdk.javadoc/share/classes/jdk/javadoc/internal/doclets/toolkit/resources/stylesheet.css
Add ".ui-autocomplete .result-item {...}".
Please review this carefully.

src/jdk.javadoc/share/classes/jdk/javadoc/internal/doclets/toolkit/util/DocPaths.java
I added JQUERY_UI_STRUCTURE_CSS by hand. The context contains JSZIP paths that are not in 17.

test/langtools/jdk/javadoc/doclet/testSearch/TestSearch.java
test/langtools/jdk/javadoc/tool/api/basic/APITest.java
Again, jszip files in the context.

Added edits also to test/langtools/tools/javadoc/api/basic/APITest.java
