move ui loop out of hw/pvr
vk: implement multi-rendering, delay swap. Load fb before render pass
fps counter now counts frames, not renders
vk: force ignoreTexAlpha for 565 texture in case the supporting texture
has an alpha channel (RTT). Fixes Alone in the Dark cinematic scenes.
pvr: better detection of frame swapping (FB_R_SOF/FB_W_SOF)
pvr: synchronous rendering now always waits for render in progress
(speed measurement not reliable, render skipped when multi-rendering)
vk: limit swap chain size to 2
Get rid of the renderer thread. It is now the main/UI thread on all
platforms. The emulator runs in a separate thread.
