backend/native: Only disable KMS modifiers for i915 The intel DRM driver is known for not being able to handle multi head setups when KMS modifiers are enabled, due to the implicitly selected modifiers, while being more suitable for single head setups, cause bandwidth issues when a certain number of monitor times resolution and refresh rate is configured. We don't yet support automatically finding a combination of modifiers that work, and have because of this disabled KMS modifiers unless the driver actually needs it. Lets flip this configuration the other way around, changing the current udev rule to decide wen to *disable* KMS modifier support, as it so that only the Intel driver has this problem, while on the other hand, there several drivers that requires modifiers to function at all.

backend/native: Disable KMS modifiers for amdgpu and nouveau as well Lets wait until we have better ways to unredirect client buffers before we start enabling KMS modifiers for amdgpu and nouveau; we end up with mismatch between client buffer modifiers and primary plane modifier, which right now needs to be the same for unredirection.

backends/native: Disable KMS modifiers on "radeon" driver This is a driver for old AMD/ATI GPUs and doesn't seem to support modifiers. Tag this driver as not having support for KMS modifiers.

udev-rules: Use ID_PATH to detect vkms Matching against the driver doesn't seem to work, and isn't showing in udevadm info. Switch to checking ID_PATH; hopefully it won't change too often. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1892>
