Module linux 

GL framebuffer import via Vulkan external memory (Linux/Android).

Imports a GL framebuffer into a wgpu::Texture by:

1. Creating a Vulkan image with external memory (opaque FD)
2. Importing the FD into GL via GL_EXT_memory_object_fd
3. Blitting from the source FBO to the shared GL texture
4. Wrapping the Vulkan image as a wgpu::Texture
