Packaging updates and notes for downstreams

• The CI has been set up to notify Codecov about upload completion
  -- by :user:webknjaz.

  With this, Codecov no longer needs to guess whether it received all
  the intended coverage reports or not.

• The in-tree build backend allows the end-users appending
  CFLAGS and LDFLAGS by setting respective environment
  variables externally.

  It additionally sets up default compiler flags to perform
  building with maximum optimization in release mode. This
  makes the resulting artifacts shipped to PyPI smaller.

  When line tracing is requested, the compiler and linker
  flags are configured to include as much information as
  possible for debugging and coverage tracking. The
  development builds are therefore smaller.

• The :pep:517 build backend now supports a new config
  setting for controlling whether to build the project in-tree
  or in a temporary directory. It only affects wheels and is
  set up to build in a temporary directory by default. It does
  not affect editable wheel builds — they will keep being
  built in-tree regardless.

  Here's an example of using this setting:

  .. code-block:: console

  $ python -m build
  --config-setting=build-inplace=true

• Starting this version, when building the wheels is happening
  in an automatically created temporary directory, the build
  backend makes an effort to normalize the respective file
  system path to a deterministic source checkout directory.

  -- by :user:webknjaz

  It does so by injecting the -ffile-prefix-map compiler
  option into the CFLAGS environment variable as suggested
  by known reproducible build practices <https://reproducible-builds.org/docs/build-path/>__.

  The effect is that downstreams will get more reproducible
  build results.

• Dropped Python 3.9 support; Python 3.10 is the minimal supported Python version

• The CI has been updated to consistently benchmark optimized
  release builds -- by :user:webknjaz.

  When the release workflow is triggered, the pre-built wheels
  ready to hit PyPI are being tested. Otherwise, the job
  builds the project from source, while the rest of the
  workflow uses debug builds for line tracing and coverage
  collection.
