libcamera: software_isp: debayer_egl: Make DebayerEGL an environment option

Browse source 
If GPUISP support is available make it so an environment variable can
switch it on.

Given we don't have full feature parity with CPUISP just yet on pixel
format output, we should default to CPUISP mode giving the user the option
to switch on GPUISP by setting LIBCAMERA_SOFTISP_MODE=gpu
