DBZ BT4 2.5 — native only, no PCSX2 in the pack

What's new

No more PCSX2 in the Windows pack. The runtime's own Vulkan renderer (with DLSS / FSR 2) was already the only quality, so the PCSX2 GS host is gone from the pack: 95 → 82.5 MB, 181 → 27 files. Recomp 3.4.4 installs it by itself (it updates itself first).

Vulkan window on every PC. 2.4.1 made the game's window Vulkan's to fix the black fullscreen. 2.5 makes sure that works everywhere:

• On laptops with two GPUs, the game now asks the driver for the dedicated GPU (NVIDIA Optimus / AMD switchable graphics), so OpenGL and Vulkan run on the same one.
• Before creating the window, the game checks that Vulkan can show what OpenGL draws (same GPU, interop extensions). If it can't, the window stays OpenGL's and is presented as before 2.4.1, instead of staying black.

Also in the runner (the Mac session's layers, now in the Windows build too): pipewarm (pipeline prebuild, on by default only on macOS; PS2X_PIPEWARM=1 to try it on Windows) and macwait (macOS frame timing; no effect on Windows). Built with profile-guided optimisation.

Online: nothing in the game state changed, so 2.5 plays online with 2.4 / 2.4.1 and with the Mac app.

macOS: DBZ_BT4_Mac.zip is the Mac app 3.4.3 (no stalls on first use of effects, steady 60 fps). Recomp on a Mac updates itself to it.

You need your own ISO (SLUS-219.78, Beta 14 Rev2); nothing from the disc is included.

Build notes: patches/bt3recomp-bt4mod-vkcheck.patch and windows/make_dist.ps1 (docs/BUILDING.md).
