feat: explicitly add NVIDIA GPU RuntimeClasses

Add NVIDIA GPU shims with TEE protection to the default values.yaml:
- kata-qemu-nvidia-gpu-snp: GPU with AMD SEV-SNP protection
- kata-qemu-nvidia-gpu-tdx: GPU with Intel TDX protection

Update README.md and QUICKSTART.md to document these RuntimeClasses
as part of the standard x86_64 installation.
