This is necessary on Windows because some applications such as Bazel/Docker do not understand/handle Linux-like paths that msys uses.
The script first converts all `JAXCI.*DIR` variables containing msys-like paths to Windows paths using cygpath. Then it sources those variables into the shell environment so that any tools that use those variables can run correctly.

This commit adds the new CI scripts for running Pytests. It makes use of the pytest envs inside the "ci/envs/run_tests" folder to control the build behavior. For e.g: for running the GPU tests with Pytest, we will need to run `./ci/run_pytest.sh ./ci/envs/run_tests/pytest_gpu.env`. Note that Pytests need JAX wheels to be installed on the system to work. The `install_wheels_locally.sh` script installs these wheels in CI builds.

This commit introduces new CI scripts and environment files for building JAX artifacts. It makes use of the artifact envs inside the "ci/envs/build_artifacts" folder to control the build behavior. For e.g: for building jaxlib, we will need to run `./ci/build_artifacts.sh ./ci/envs/build_artifacts/jaxlib.env` from the JAX GitHub root.

This commit introduces new CI scripts and environment files for running Bazel CPU presubmits.
* Adds a ci directory at the root of the repository to store these files.
* Environment files are located in ci/envs and define new JAXCI_ environment variables to control CI build behavior.
* The build script sources these environment files and set up the build environment before running the build commands.
