devel/py-find-libpython: update 0.3.1 → 0.4.0

Reported by:	portscout

devel/py-setuptools-scm: update to 8.0.4

Directory and PORTNAME changed to match normalised name in release
tarball; consumers updated to match.

Although setuptools itself is specified as a run dependency in the
Python package metadata, it is currently left out here to prevent
environment pollution until at least PR 270510 is committed.
Additionally, this version of setuptools-scm requires setuptools>=61,
which means this version is only meant for USE_PYTHON=pep517 ports
as all USE_PYTHON=distutils ports will switch to devel/py-setuptools58
also after PR 270510. science/py-emmet-core is switched to
devel/py-setuptools_scm7 accordingly, as it specifies setuptools-scm<8.
devel/py-{flit-scm,hatch-vcs} have ${PY_SETUPTOOLS} added to
RUN_DEPENDS to compensate.

USE_PYTHON=pep517: bump PORTREVISION

Revert "Mk/Uses/python.mk: Fix USE_PYTHON=pep517: always compile and install
bytecode"

Despite installer's default behaviour to compile and install bytecode,
we are not doing so going forward at stage/package time. [0] During
initial development and qualification of PEP-517 framework support,
compiling and installing bytecode at stage/package time was considered,
but was found problematic, fragile and ultimately unreliable, both
currently and historically (with USE_PYTHON=distutils), due to our
fixed plist requirement. While the living binary distribution format
(wheel) specification [1] says to compile bytecode, that is in the
pure Python package management context (pip, etc); nuance always
exists when interacting with "system" package management.

Additionally, "bytecode is an implementation detail of the CPython
interpreter. No guarantees are made that bytecode will not be added,

Mk/Uses/python.mk: Fix USE_PYTHON=pep517: always compile and install bytecode

- While I'm here, use long options for easier reading [1][2]
- Bump PORTREVISION of dependent ports (USE_PYTHON=pep517) for package change

It fixes build_fs_violation of dependent ports in poudriere (with -t flag).
It is also the default behavior of installer [2].

from py-sphinx log:
=>> Checking for staging violations... done
=>> Error: Filesystem touched during stage (files must install to ${STAGEDIR}):
extra: usr/local/lib/python3.9/site-packages/importlib_metadata/__pycache__
=>> Cleaning up wrkdir

from installer documentation:
--compile-bytecode
    Possible choices: 0, 1, 2
    generate bytecode for the specified optimization level(s) (default=0, 1)
--no-compile-bytecode
    don’t generate bytecode for installed modules
    Default: False
