.github: use the linux-modules-kpd files to unify a branch

Each linux-foo-kpd tree right now uses its set of code but this is
efficient. We'ven striving to allow sharing as much as code as possible.
This branch allows any linux-foo-kpd to use this tree as follows:

on:
  push:
    branches: ['**']
  pull_request:
    branches: ['**']
  workflow_dispatch:  # Allow manual triggering

jobs:
  kdevops-workflow:
    uses: linux-kdevops/kdevops-ci/.github/workflows/kdevops.yml@unified-kpd-tests
    secrets: inherit
