Subject: [PATCH] fix(hwaccel): add libmfx-gen1.2 to Intel Arc setup for QSV
 support (#11707)

Add missing libmfx-gen1.2 package to _setup_intel_arc() for both
Ubuntu and Debian. Without this package, QSV hardware acceleration
fails with 'Error creating a MFX session: -9'.

The package was already present in _setup_intel_modern() (Gen9+)
but missing from the Arc GPU path.

Closes #11701
