[Buildroot] [PATCH v2 8/9] package/python-pkg-resources: new host package

[James Hilliard <james.hilliard1@gmail.com>]

Setuptools 82 removed pkg_resources, but older U-Boot Binman versions
still use it. Package the standalone PyPA snapshot so these consumers
can keep working when setuptools is updated.

Add a small setuptools pyproject.toml to build the module from its
repository-root layout, and include the license addition proposed
upstream. Supply packaging, jaraco.text and platformdirs explicitly,
as the standalone module imports all three at runtime.

Add a host runtime test covering resource access, dependency resolution
and cache lookup.

+Subject: [PATCH] Add build metadata for the standalone package
+
+Build the extracted pkg_resources module as a standalone wheel, mapping
+the package to the repository root. Use a static version for this snapshot
+so building an archive does not need setuptools-scm or Git metadata.
