Detect Hyprland software rendering from the GL renderer

Carry a v0.56.2 backport of hyprwm/Hyprland#16343 so display-only KMS
drivers paired with llvmpipe are classified as software rendering.

+
+Backport-of: 61d0ff60a7547d49229714a68b7ca9c0b6658727
+Upstream-PR: https://github.com/hyprwm/Hyprland/pull/16343
+Co-authored-by: Eryk Wieliczko <44800858+erykwieliczko@users.noreply.github.com>
+
+Adapt constructor and logger-context differences against v0.56.2 while
+preserving the original GL classification behavior. Remove this backport
+once the packaged upstream version includes this behavior.
