fix(linux/kms): skip NVIDIA cards for VAAPI on hybrid GPU laptops

[coleleavitt]

Description

Skip Nvidia cards if we're looking for VAAPI devices. This is important for hybrid GPU laptops where the display may be connected through NVIDIA but rendering happens on Intel.

Pull request overview

This PR adds logic to skip NVIDIA graphics cards when searching for VAAPI-capable devices in KMS (Kernel Mode Setting) display capture. This is particularly important for hybrid GPU laptops where the display may be connected through an NVIDIA GPU but hardware encoding should occur on the Intel/AMD GPU that supports VAAPI.

Key Changes

• Added NVIDIA card filtering for VAAPI device enumeration in two critical locations within kmsgrab.cpp
• The filtering occurs during both display initialization and display name enumeration
• Debug logging added to track when NVIDIA cards are being skipped for VAAPI

The base branch was changed.
