This is due to a change in the bazel-6 package.

* guix-science/packages/python.scm (python-jaxlib/wheel): Update hash
of vendored sources.

* guix-science/packages/python.scm (bazel-vendored-inputs): Accept
argument extra-configuration; remove configuration specific to jaxlib.
(python-jaxlib/wheel)[arguments]: Pass value to bazel-vendored-inputs
via extra-configuration.

* guix-science/packages/bazel.scm (bazel-6)[arguments]: Patch Python
toolchain templates.

* guix-science/packages/bazel.scm (bazel-6)[source]: Delet some
bundled jars.
[arguments]: Add phase 'prepare-jars.
[inputs]: Remove java-asm, java-commons-lang3, java-commons-pool,
java-fasterxml-jackson-core, java-guava, java-gson, and java-junit;
add java-commons-io, java-commons-lang, and java-hamcrest-core.

*
guix-science/packages/python.scm (eigen-for-python-ml-dtypes)[arguments]:
Disable tests.

This is for eigen.

* guix-science/packages/python.scm (python-jax): New variable.

This commit adds what might later become a generic bazel-build-system.
BAZEL-VENDORED-INPUTS is a procedure that uses Bazel to compute a
source code bundle for a given configuration.  This bundle is then
used as an input in the actual package where Bazel is convinced to
accept the bundle instead of fetching source code over the internet
all over again.

* guix-science/packages/python.scm (bazel-vendored-inputs): New
procedure.
(python-jaxlib/wheel, python-jaxlib): New variables.

* guix-science/packages/python.scm (eigen-for-python-ml-dtypes): New
variable.
(python-ml-dtypes): New variable.
