The new release:

• fixes java_tools' ijar and singlejar don't build on windows bazel#8614
• exposes a new toolchain @java_tools//:prebuilt_toolchain which is using all the pre-built tools, including singlejar and ijar, even on remote execution. This toolchain should be used only when host and execution platform are the same, otherwise the binaries will not work on the execution platform.

This issue follows the java_tools release process.
