The name of the class is overly long. If you look at the other classes in
oe-core, they basically use the build-backend value,
prefixed with the "python_" namespace, so I would propose just
"python_mesonpy.bbclass"

The python_setuptools_build_meta.bbclass was named as such because the
build-backend is "setuptools.build_meta"
such as in https://github.com/jaraco/zipp/blob/main/pyproject.toml#L3
