Add real PinMAME (VPinMAME.Controller) integration for ROM-based tables

Statically links the real PinMAME emulation core (libpinmame) instead of
leaving VPinMAME.Controller creation to fail, which was crashing table
scripts on ROM-based tables before they could spawn a ball. PinMAME's own
run_game()->cpu_run() loop is split into a one-shot init, a per-frame step,
and a one-shot teardown (patches/pinmame/0004) so it runs cooperatively on
the same frame callback as vpinball's own loop instead of on a real
std::thread, which hard-aborts under Emscripten's single-threaded runtime -
three smaller wasm32 portability fixes to libpinmame itself round out the
patch set (0001-0003). Adds pinball.loadRom() to supply a ROM zip, written
to the table-relative pinmame/roms/ path vpinball's own plugin already
checks. Confirmed against a real community ROM-based table: Controller
creation and game identification succeed, and a missing ROM now fails
cleanly instead of crashing the page - actual ROM-driven gameplay is still
unconfirmed since no ROM was available (or sought out) to test with.
