Summary [GTK][WPE] Support Vivante super-tiled format for MemoryMappedGPUBuffer

We currently only support linear formats for the dma-buf backing the MemoryMappedGPUBuffer, and would like to extend that to more "exotic formats", that are common on platforms that we support, such as i.MX6/8. We sample textures in GL_LINEAR (instead of GL_NEAREST) mode, thus using MemoryMappedGPUBuffers, backed with linear dma-bufs, has a non-negligible cache hit rate, leading to an increased memory read bandwidth. We could avoid that if we can directly create GPU-cache-friendly memory layouts, such as Vivante super-tiled.
