Subject: CI: Extract the OpenWrt building to own sub workflow

Extract the building of OpenWrt into an own workflow which is then
triggered by the kernel.yml and packages.yml workflow with different
inputs. This allows us to share much of the code of the workflow.

Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
(cherry picked from commit 7c406a5f0837b0bfc293b723932695176a8ef6fe)
