feat(mlnx-ofa_kernel): add userspace mlnx-ofa_kernel package

[ellie-di]

This PR adds the mlnx-ofa_kernel userspace component to Azure Linux, bundled with a post-transaction hook that automatically installs matching kernel module versions when the kernel upgrades on systems where the kmod is already in use.
The matching kernel module is added in PR: feat: add mlnx-ofa_kernel kernel module

[Copilot]

Pull request overview

This PR adds a new local-spec component, mlnx-ofa_kernel, providing the userspace half of NVIDIA/Mellanox OFED support (openibd init script/units, interface-manager scripts, modprobe configs, udev rules, and the pristine driver source). It complements the kernel-module half added in PR #17780. The package also ships a libdnf5 post_transaction actions hook plus a helper script (mlnx-ofa-kmod-autoupdate) that, after a kernel upgrade, auto-installs the matching kmod-mlnx-ofa_kernel build when the kmod was already in use.

Changes:

• New component definition (mlnx-ofa_kernel.comp.toml): local spec, release.calculation = "manual", and a downloaded MLNX_OFED_SRC source bundle (shared with the kernel component).
• New local spec that unpacks the inner mlnx-ofa_kernel SRPM from the OFED bundle and installs userspace scripts/units/configs plus a -source subpackage.
• A dnf5 actions hook (.actions) + mlnx-ofa-kmod-autoupdate.in script for post-kernel-upgrade kmod auto-install, with the rendered specs and lock file checked in.
