Commit 3da874371 ("libsodium: include ed25519_core in minimal build")
broke the build of PyNaCl. Add patch to always include all ed25519
functions which are now always covered even if libsodium is built with
the MINIMAL option.

The crude loop I wrote to come up with this changeset:

  find -L package/feeds/packages/ -name patches | \
  sed 's/patches$/refresh/' | sort | xargs make

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.

Fixes https://github.com/openwrt/packages/issues/13016
Patch [1] broke compilation for python-pynacl.

The fix is to patch PyNaCl to consider that
PYNACL_HAS_CRYPTO_SCALARMULT_ED25519 is always available.

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

These packages were in the PR stage when the cleanup occurred and so
still had VARIANT:=python3.
