mesa: scope down to essential drivers (swrast, virgl, crocus, iris)

- Remove radeonsi (needs libdrm_radeon, disabled in libdrm)
- Remove amd vulkan (needs LLVM amdgpu module, dl_iterate_phdr)
- Remove intel vulkan (needs dl_iterate_phdr, not in relibc)
- Remove zink (needs full Vulkan infrastructure)

Kept: swrast (LLVMpipe), virgl (QEMU virtio-gpu 3D), crocus + iris
(Intel Gen4-Gen12+ Gallium 3D). These are the two primary 3D driver
targets for the desktop path.
