Use pip --use-feature=in-tree-build, replace use of sdh_setup_bdist_wheel by sdh_pip_install #32046
Description
This is a feature added in pip 21.1.
We can now build wheels for all packages using pip wheel, even those with symlinks or that need in-tree configuration files. Direct invocation of setup.py bdist_wheel is no longer necessary.
