D335: native widescreen, HUD + front end (Option B Phase 3)

Browse Source 
HUD elements now keep 4:3 proportions via fast3d's EXT aspect modes (the PD
pattern): watch, gauge bars, messages/title card, upper text and countdown
CENTER; ammo RIGHT (right hand) / LEFT (left hand). The front end is
pillarboxed (whole menu_jump_constructor_handler CENTER) and the menu
pointer is mapped into the pillarbox. port/include/hudaspect.h emits only
when native widescreen is on and the window is wider than 4:3, so 4:3 and
native-off stay byte-identical. Rule-2 approved.

Verified with 16:9/21:9 captures (HUD, watch, title card, legal, file
select, gun barrel); golden 3/3; Win + Linux builds. Gun-barrel circle
leaks into the bars while sliding in -> GRAPHICS-BACKLOG D335a.

/* D335 (WIDESCREEN-FOV-PLAN Option B, Phase 3): HUD alignment under native
* widescreen (D334). The world is projected at the window aspect, but 2D/HUD
* elements are laid out in the game's 4:3 logical canvas, which fast3d
* stretches to the window. Wrapping a HUD draw in an aspect mode makes fast3d
* map its x undistorted (x scaled by (4/3)/window_aspect) and anchor it to
* the left edge, the right edge, or the centre -- the PD port's
* G_ASPECT_{LEFT,RIGHT,CENTER}_EXT extra-geometry-mode, which GE's fast3d
* already decodes (gfx_pc.cpp gfx_sp_extra_geometry_mode /
* gfx_update_aspect_mode). Game-includable: no SDL, no fast3d headers.
*
* PORT_HUD_ASPECT emits only while native widescreen is on and the window is
* wider than 4:3; otherwise the display list is byte-identical to before. */
