feat(windows): a window - win32.ll, WGL on it, and a windowed Windows build

Browse source 
win32.ll implements cocoa.ll's contracts over user32 and xinput: the message
pump, the held-key set and frame key in Ludic codes, the mouse with raw input
for cursor mode 2, clip-based cursor modes released on focus loss, XInput pads,
and the software framebuffer present. win32_gl.ll puts the WGL 4.1 core context
on that window (vsync, borderless full screen); gl_win.ll's context code is now
lgl_wgl_core, shared with the headless hidden window, whose win_gl_* stubs move
to gl_win_nowin.ll. audio_win.ll links Audio.* silently for now.

Verified: macOS fixpoint, ludic-dev test 135/135, selfhost-test 32/32; on the
PC gl_triangle renders identically headless and in a real window, and Maroon
Lake builds windowed and runs a playtest to frame 240 in the desktop session.

; ============================================================================
; gl_win_nowin.ll — the window half of Gl.* in a headless Windows build.
;
; gl.ludic names win_gl_* on its is_windowed() branch. A headless build compiles that
; branch to nothing, but the names still have to resolve; a windowed build links
; win32_gl.ll, which defines them on the real window, in place of this file.
