ci: Add OneAPI artifact build script and auditwheel support

[ashahba]

Summary

This PR adds CI infrastructure to build Intel GPU (oneAPI) JAX wheels and verify their manylinux compliance.

• ci/build_oneapi_artifacts.sh: New script to build jax-oneapi-pjrt and jax-oneapi-plugin wheels. Follows the same structure and conventions as the existing build_artifacts.sh, supporting default, nightly, and release artifact types, RBE, and remote Bazel cache.
• ci/utilities/run_auditwheel.sh: Add jaxoneapipjrtwhl and jaxoneapipluginwhl patterns so that manylinux compliance is verified for oneAPI wheels alongside existing CUDA and ROCm wheels.

Test Plan:

• ./ci/build_oneapi_artifacts.sh jax-oneapi-pjrt builds successfully
• ./ci/build_oneapi_artifacts.sh jax-oneapi-plugin builds successfully
• auditwheel passes for the produced oneAPI wheels

Code Review

This pull request introduces support for building JAX OneAPI artifacts (jax-oneapi-plugin and jax-oneapi-pjrt) by adding a new build script, defining the default OneAPI version in the environment configuration, and updating the auditwheel utility to verify the compliance of the new wheels. The review feedback suggests validating the artifact parameter early in the build script to avoid a deeply nested conditional block, and using Bash's built-in parameter expansion instead of spawning a subshell for basename in the auditwheel script.
