[24] JEP 494: Module Import Declarations (Second Preview)

JLS Changes at: https://cr.openjdk.org/~gbierman/jep494/latest/
https://bugs.openjdk.org/browse/JDK-8335987

Summary
Enhance the Java programming language with the ability to succinctly import all of the packages exported by a module. This simplifies the reuse of modular libraries, but does not require the importing code to be in a module itself. This is a preview language feature.

History
Module import declarations were first proposed as a preview feature by JEP 476, and delivered in JDK 23.

JEP 476 support in jdt.core is captured in issue #2383
