Remove usages of the Turbine graal native image for `darwin_x86_64`

From https://www.graalvm.org/release-notes/JDK_25 : `Support for macOS x64 has been removed. Version 25.0.1 was the last release that supported this hardware architecture. GraalVM now only supports macOS on AArch64 (Apple Silicon).`

Prepares for dropping it from the next `java_tools` release, which is currently broken after https://github.com/bazelbuild/bazel/pull/30228
