Enable path mapping for JavaDeployJar

Enable execution_requirements = {"supports-path-mapping": "1"} on the JavaDeployJar action registration in rules_java across all deploy JARs.

Map each hermetic resource to its configuration-independent `short_path` using SingleJar's `<source_path>:<zip_path>` syntax and set `--hermetic_java_home` to `runtime.java_home_runfiles_path`. This allows path mapping to be safely enabled unconditionally across both hermetic and non-hermetic deploy JARs.
