python3-wxgtk4: Use python_setuptools_build_meta

pyproject.toml specifies setuptools.build_meta as the build backend.
Inheriting setuptools3 with INSANE_SKIP for pep517-backend was a
workaround for the top level build.py shadowing pyproject-build's own
"build" module, which is fixed in oe-core's python3targetconfig class
("python3targetconfig: Do not add the current directory to PYTHONPATH").

pyproject.toml pins sip == 6.12.0, which is only used to regenerate the
wrapper sources that the sdist already ships, so skip the build
dependency check.
