* [VideoOut/Vulkan] Fix boot deadlock, writeback stall, and presentation bugs - Presenter thread now starts on the compute dispatch path too, fixing a boot deadlock when a title's first GPU work is compute (Ghost of Yotei G-Buffer clear). - Guest render-target format swaps between sibling pixel formats now reinterpret in place instead of recreating blank, preserving GPU-written content. - Vectorized the guest-buffer writeback scan (equal-byte skip + coarse per-page pre-check), fixing multi-second stalls on fragmented buffers that starved JobWorker completion signals. - _presentedSequence now advances on every Render() early-return path, fixing an unthrottled busy loop on stale/dropped presentations. * Remove unnecessary Silk.NET.Windowing dependency
