Subject: build: Make use of Gradle's Java Toolchains feature

This change updates the build configuration for Gradle to make use of
its Java Toolchains feature which enables running/testing multiple Java
versions at the same time. This feature can also provision a Java
installation if it is not available on the user's system.
