Widescreen experiment: native render size via dxwrapper, classic menus

- mods/widescreen: redirect the world view's reads of the 1024.0/768.0
  constants and the 3D ortho extents to our variables; render size =
  monitor; relocate the world view's tile draw list (1750 entries, no
  bounds check) into an enlarged object (16384 entries).
- mods/dxwrapper: route DirectDraw through dxwrapper (Dd7to9, D3D9) since
  Windows' D3D7 cannot render to targets larger than 2048; fix the game's
  device info GUID pointer that dxwrapper's enumeration leaves invalid.
  Pinned release fetched by CMake (hash-checked), installed next to the DLL.
- Main menu (UI thread) and loading screen render in a 1024x768 viewport
  and are presented scaled ("classic" layout); in-game uses the full size.
- re/patch: verified code patches (operand redirect, push immediates,
  displacements) and startup hooks; build.ps1/CMake download fixes.

In-game view untested yet; HUD still at the top-left.
