feat: dynamically set GPU variable in chromium.conf

[symbiogenesis]

seems logical to determine this dynamically, just as the wayland state is

tested that it adds the appropriate flags and features from the case statement below on my machine in chrome://version

[symbiogenesis]

Maybe some of the changes in this file like the dynamic wayland detection could be upstreamed?

I like this in principle but this would mean taking a hard dependency on egl-utils, which I'm opposed to. Is there a way we can accomplish this without introducing a new package dependency?

[RoyalOughtness]

also, this will have issues on multigpu systems, where we will need to know which gpu chromium is actually going to run on

It's a good change but sigificantly too early. The AMD config is still early since Chromium vulkan support is still in development, and the Nvidia config is also indifferent since the Nvidia VAAPI flag is experimental (last I checked it does nothing). And as @qoijjj mentioned, idk how this would fly on multi-gpu setups.

A note on the status of the Nvidia flag:

May be able to update this using lspci and then fallback to default on heterogeneous multi-GPU setups.

i.e.

GPU_INFO=$(lspci | grep -E "VGA|3D" | grep -o -i -E "amd|intel|nvidia" | sort -u | tr '[:upper:]' '[:lower:]' | xargs)
if [ $(echo "$GPU_INFO" | wc -w) -gt 1 ]; then
    GRAPHIC_DRIVER="default"
else
    GRAPHIC_DRIVER=${GPU_INFO:-default}
fi
