Refactor JAX's .bazelrc
This is the first step as part of the JAX CI rework project.
Changes:
* Adds new `ci_{os_name}_{arch}` configs that consolidates the different configs that we use in CI builds under a single config.
* Consolidates Python specific RBE Linux CPU and RBE Linux CUDA configs into Python agnostic `rbe_linux_x86_64` and `rbe_linux_x86_64_cuda`. These new RBE configs inherit the settings in the corresponding `ci_` config and pass in additional RBE specific flags such as platform details, remote execution backend, and authentication details. Hermetic Python version details will now be passed directly in the CI build scripts.
* Adds new RBE Windows configs.
* Removes JAVA flags from RBE configs. These are ignored from Bazel 5+. (See related TF PR: https://github.com/tensorflow/tensorflow/pull/54547)
* Renames some configs: `cuda_nvcc` is now `build_cuda_with_nvcc`, `cuda_clang` is now `build_cuda_with_clang`, `rbe_cross_compile_macos_x86` is now `rbe_cross_compile_darwin_x86_64`, `rbe_cross_compile_linux_arm64` is now `rbe_cross_compile_linux_aarch64`.
* Separates platform specific configs and feature specific configs into their own section.
* Removes unused `--define` configs
* Adds new test configs that will be used when running `bazel test`. `non_multiaccelerator` will be used in RBE Linux CUDA test builds, `non_multiaccelerator_local` and `multiaccelerator_local` will be used in Linux CUDA test builds which depend on local jaxlib and plugin wheels instead of building them along with the rest of the test targets.
* Replaces `--spawn_strategy=standalone` with `--spawn_strategy=local`. `standalone` has been [deprecated by Bazel](https://bazel.build/docs/user-manual#spawn-strategy).
