[GPU] F10 ship-placement capture: dump world-space draw vertices for RE

Browse Source 
One-shot snapshot for reversing capital-ship part placement. F10 arms
RequestShipCaptureFrame(); the next batch of draws is dumped to
xenia_ship_capture.log with each draw's guest vertex-buffer address, vertex/
index counts, and up to 64 WORLD-space vertex positions. Capital-ship parts are
transformed into world space before the draw (unlike stage geometry, which
matches the .xpr byte-for-byte), so these are ground truth for the assembled
placement; a reborn-side correlator affine-fits each decoded .xpr part to a
captured draw to recover its exact transform. De-duped by buffer address, gated
independently of the log_draws cvar, budget-capped at 8000 draws / 4096 buffers.
