This still causes gpui to be unusable for Intel Macs and by extension
Zed.

Third attempt to land this improvement: (#45577, #44273)

The previous PR didn’t work on Intel MacBooks because I made a wrong
assumption about the unified memory check. `has_unified_memory` only
tells us that the CPU and GPU share memory. It does not mean we’re
running on an Apple GPU family.

Memoryless textures are only supported on Apple GPUs. Some Intel Macs
report unified memory, but they don’t support memoryless textures, which
is why the previous change failed there.

So instead of relying on unified memory, we now explicitly check that
we’re running on an Apple GPU family before enabling memoryless
textures.
