Fixing build for fully homomorphic encryption repo

[code-perspective]

WIP
This pull request updates the WORKSPACE file to address dependency management issues and improve repository initialization. The key changes include adding support for Python rules, loading additional dependencies, and reordering initialization calls to resolve errors.

Dependency Management Enhancements:

• Added rules_python to the WORKSPACE file to resolve an AttributeError related to pkgutil.ImpImporter. This includes specifying the version and SHA256 checksum for the Python rules archive.
• Loaded additional dependencies using grpc_extra_deps and xls_pip_install_deps to address missing package errors related to @xls_pip_deps_markupsafe.

Still running into a similar error which (I think) needs python 3.11 version. because pkgutil was removed from python 3.12

^^^^^^^^^^^^^^^^^^^
AttributeError: module 'pkgutil' has no attribute 'ImpImporter'. Did you mean: 'zipimporter'?

Ted's patches to get xls to build after adding as external dependency seems to work! https://github.com/ted-xie/xls_as_external_dep/tree/main

bazel run //transpiler/examples/simple_sum:simple_sum_cleartext_testbench works
