Haiku enables AVX512 support

We're a little deep into June already, but it's only now that Haiku published its monthly progress report for May. There's a bunch of fixes for drag-and-drop behaviour in Tracker, AVX512 support can now be enabled thanks to changes to the kernel's FPU handling, some low-level changes were made for the Rust and Zig compilers, and further improvements were made to the boot process on the Raspberry Pi 5 (although a lot more work is needed on that front).

There's still no sixth beta since a few more blockers remain, but don't let that stop you from installing Haiku - it's stable enough as it is, sixth beta or no.
