Add Debian package mappings for the Qualcomm graphics overlay and upstream Mesa/freedreno base stack. Add package-set verification and removal helpers to: - avoid package-manager work when a set is already complete - remove installed overlay packages when restoring the base stack - validate package contents required by graphics backends - report whether a package transition requires reboot Signed-off-by: Srikanth Muppandam <smuppand@qti.qualcomm.com>
Add reusable helpers to: - detect MSM/freedreno and KGSL GPU boot ownership - identify unsafe KGSL reload failures - validate the requested GPU boot mode - remove stale KGSL boot configuration - select the Mesa or Adreno GLVND EGL vendor - stop and restore display-manager DRM ownership safely Signed-off-by: Srikanth Muppandam <smuppand@qti.qualcomm.com>
Extend the KMSCube test to support both graphics configurations: - use upstream MSM/freedreno by default - enable Qualcomm KGSL and Adreno with --overlay - install or remove the required package sets - request reboot when GPU ownership changes - verify the Qualcomm GBM backend - select the correct EGL vendor - preserve native graphics handling on Yocto images - release and restore DRM ownership around KMSCube - retain modetest output for display diagnostics Signed-off-by: Srikanth Muppandam <smuppand@qti.qualcomm.com>

Extend the KMSCube testcase to validate both supported Qualcomm graphics configurations on Debian-based systems:
The testcase now manages the required package stack, validates the active GPU boot ownership, selects the correct EGL vendor, and safely handles DRM ownership before running KMSCube.
