Use optimal tiling for the drawable GL import on NVIDIA

Browse Source 
NVIDIA's GL rejects GL_LINEAR_TILING_EXT with GL_INVALID_VALUE, so the
linear internal image could not be imported and the window stayed black.
Pick the tiling by GL_VENDOR; other drivers keep linear.

The first import of a drawable into the presenting OpenGL context, and the first semaphore import, are logged too; later ones only when they fail (at most five):
```

A non-zero error or `FAILED` means the frames cannot reach the window. Before 2026-10-16 the import did not mark the memory as dedicated, which the extension requires; Mesa ignores it, and it is the suspected cause of the NVIDIA black screen (not yet confirmed). If the game shows a black screen on NVIDIA, report it with this file.
A non-zero error or `FAILED` means the frames cannot reach the window. Before 2026-10-16 the import did not mark the memory as dedicated, which the extension requires; Mesa ignores it, and it is the suspected cause of the NVIDIA black screen (not yet confirmed). An NVIDIA log of 2026-10-16 showed `glTiling=optimal` with `setup_error=0x501 storage_error=0x501 FAILED`: NVIDIA's GL rejects `GL_LINEAR_TILING_EXT`, so the linear Vulkan image could not be imported. Since then the internal image and the GL texture use optimal tiling when `GL_VENDOR` contains NVIDIA (`vkTiling=optimal glTiling=optimal ok` is the expected line); everything else keeps linear. If the game shows a black screen on NVIDIA, report it with this file.
