This also removes PKG_BUILD_PARALLEL:=0 that was added for packages that
use HOST_PYTHON3_PACKAGE_BUILD_DEPENDS.

In hash-checking mode[1], pip will verify downloaded package archives
(source tarballs in our case) against known SHA256 hashes before
installing the packages.
As a consequence, this requires the use of requirements files[2] and
pinning packages to known versions.
The syntax for package Makefiles has changed slightly;
HOST_PYTHON3_PACKAGE_BUILD_DEPENDS no longer accepts requirement
specifiers like "foo>=1.0", only requirements file names (which are the
same as package names in the most common case).
This also updates affected packages, in particular:
* python-zipp: "setuptools_scm[toml]" has been split into
"setuptools-scm toml" to reuse the requirements file for
setuptools-scm (the extra depends installed by "setuptools_scm[toml]"
is toml).
* python-pycparser: This previously used ply 3.10, whereas the
requirements file will now install 3.11.

This adds PKG_BUILD_PARALLEL:=0 to packages that depend on host Python
packages (HOST_PYTHON3_PACKAGE_BUILD_DEPENDS), because installing
packages with multiple concurrent pip processes can lead to errors or
unexpected results[1].
This also:
* Move HOST_PYTHON3_PACKAGE_BUILD_DEPENDS definitions to before
python3-package.mk is included
* Update Python folder readme to include PKG_BUILD_PARALLEL:=0
