This reverts the setup.py changes from
f28b20175f307d5a56502446a9706480126a5bd4. We actually need to fix some
more issues before releasing 0.4.9, so fix the install at HEAD in the
meantime.

[Rollback] Update required Python version to 3.9
PiperOrigin-RevId: 528905991
Add a currently undocumented jax[cuda11_pip] and jax[cuda12_pip] that depend on the pip CUDA wheels.
Add a currently undocumented jax[cuda11_local] and jax[cuda12_local] that avoid the CUDA wheel dependency.
These utils are currently shared with lax_vmap_test by importing lax_test as a
library, which is an odd thing to do.
The new package and the module within it are not built into the wheel, as these
are internal utilities for JAX's tests, not utilities for JAX users writing
their own tests.
Followup changes will add additional existing internal test utilities to this
package. This will allow removing sys.path manipulation from
deprecation_module_test and hopefully lazy_loader_test, as well as removing
the non-public test_util.py from _src to make it clearer that it should not be
used from outside JAX.

This commit changes the JAX codebase to use Python's builtin logging instead of ABSL logging. With the latter being used in JAX code as of now, the change to Python builtin logging is advised for the following reasons (among others):
- absl-py can be removed as an external dependency of JAX.
- Builtin logging brings the option of adding more log handlers, for example file handlers for log dumps or writers to different IO streams.
Logging in JAX is ported over to take place at the module level. While previously, some Python namespaces within JAX already used module-scoped logging via absl.vlog, the following idiom was adopted to provide the same functionality in Python builtin logging:
```py
import logging
logger = logging.getLogger(__name__)
logger.debug(...)
logger.info(...)
```
The builtin root logger is left untouched, which is beneficial for downstream users planning to customize the Python root logger. All JAX internal code promises to log to descendants of the top-level "jax" logger by virtue of log propagation.
The package `absl-py` was removed from JAX's install requirements, and added into its test requirements.
