The current error is very uninformative, use a proper exception to
give more information when this happens:
`In procedure map: Wrong type argument: #f`
After this patch:
`In procedure raise-exception:
ERROR:
1. &no-wheels-found`
* guix/build/pyproject-build-system.scm (&no-wheels-found): Add exception.
(install): Handle exception.

In some rare cases, the dest-path can be an elf-file, which are
unreadable by substitute*, leading to an error instead of just
continuing which makes more sense in this case.
* guix/build-system/pyproject.scm (check): Guard substitution attempt
with basic readability guarantees.

Using rename-file, the destination had to be empty otherwise it would error
out. This has been fixed by the use of copy-recursively, really merging them.
Changing this makes merge-directories mostly a duplicate of
copy-recursively, thus fully switch to copy-recursively.
* guix/build/pyproject-build-system.scm (install)
<python-hashbang>: Remove it, used only once.
<merge-directories>: Remove it, replace its calls by copy-recursively
and delete-file-recursively.

* guix/build/pyproject-build-system(check): Add python test-backend.
This will help in cases where a simple `python -m module args` call has
to be made instead of fully replacing the 'check phase, e.g. unittest
or django. This is never enabled unless #:test-backend 'python is set,
so it doesn't break anything.
As an example, the following snippet...
(arguments
(list #:phases #~(modify-phases %standard-phases
(replace 'check
(lambda* (#:key tests? #:allow-other-keys)
(when tests?
(invoke "python" "-m" "unittest"
"diff_match_patch.tests")))))))
...can be transformed like this:
(arguments
'(#:test-backend 'python
#:test-flags (list "-m" "unittest" "diff_match_patch.tests")))

* guix/build/pyproject-build-system.scm: Hide the 'delete' symbol from
the imported (guix build utils) module to avoid a naming clash warning.

Using rename-file, the destination had to be empty otherwise it would
error out. By using copy-recursively, a directory can be copied onto a
pre-existing directory, really merging them. This problem manifested
itself attempting to build the python-pyre package.
Solving #596.
* guix/build/pyproject-build-system.scm (install)
<merge-directories>: Use copy-recursively instead of rename-file.

More reliable than regular expressions.
* guix/build-system/pyproject.scm (%pyproject-build-system-modules): Add (guix build toml).
(pyproject-build): Add argument #:backend-path.
* guix/build/pyproject-build-system.scm (build): Add support for
auto-detected and override backend-path.
* gnu/packages/python-build.scm (python-tomli)[arguments]: Remove
'add-self-to-path, because it is not necessary any more.
(python-poetry-core): Same.
(python-hatchling): Same.
(python-pdm-backend): Same.
This is an experimental build system based on python-build-system
that implements PEP 517-compliant builds.
* doc/guix.texi (Build Systems): Add pyproject-build-system section.
* doc/contributing.texi (Python Modules): Mention pyproject.toml and the
PYTHON-TOOLCHAIN package, as well as differences to python-build-system.
* guix/build-system/pyproject.scm,
guix/build/pyproject-build-system.scm,
gnu/packages/aux-files/python/sanity-check-next.py,
gnu/packages/python-commencement.scm: New files.
* Makefile.am (MODULES): Register the new build systems.
* gnu/local.mk (GNU_SYSTEM_MODULES): Add python-commencement.scm.
* gnu/packages/python.scm (python-sans-pip, python-sans-pip-wrapper): New
variables.
