KASM-1190 Remove legacy GPU seeding in favour of 1.19.0 agent management

Browse source 
In 1.19.0, the provision agent dynamically assigns GPUs to containers
using capability probing (EGL, DRI3, VAAPI, NVENC, VULKAN) and
load-balancing across devices. Pre-seeding GPU run_config/exec_config
into workspace images at install time conflicts with this system and
uses removed env var names (HW3D/DRINODE replaced by
KVNC_DESKTOP_GPU_HW3D/KVNC_DESKTOP_GPU_DRINODE).

Remove setGpu(), the gpuinfo.sh detection block, the GPU yaml-merge
call in install(), and the "Use GPU on all images" install UI option.
Replace the UI option with a notice directing admins to configure GPU
acceleration in the admin panel post-install.
