gnu: python-libcst: Update to 1.6.0.

* gnu/packages/python-xyz.scm (python-libcst): Update to 1.6.0.
[source]: Add snippet to satisfy cargo-build-system.
[build-system]: Switch to cargo-build-system.
[arguments]: Import cargo-build-system, pyproject-build-system modules.
Add cargo-inputs, cargo-development-inputs.  Replace 'build, 'install
with the pyproject-build-system phases.  Add a phase after 'install for
the extra pyproject phases.  Add 2 phases to help build the project.
[native-inputs]: Add python-minimal-wrapper, python-hypothesmith,
python-setuptools-rust, python-setuptools-scm.
[inputs]: Add maturin.
[propagated-inputs]: Remove python-typing-extensions,
python-typing-inspect.
(python-libcst-minimal)[arguments]: Inherit phases from python-libcst
while still skipping the tests.
[native-inputs]: Add python-minimal-wrapper, python-setutools-rust,
python-setuptools-scm.
