feat(windows): Gl.* on Windows, through WGL and a driver-filled thunk table

Browse source

gl_win.ll creates a hidden-window WGL 4.1 core context and carries gl.ll's
float/memory helpers, with ldexp and QueryPerformanceCounter in place of the
libSystem calls. glgen now also writes gl_thunks_win.ll: the same 478 thunks,
calling through pointers that @lgl_win_load fills from wglGetProcAddress (and
opengl32.dll for GL 1.1). ludicc links the pair against opengl32/gdi32/user32
on a Windows target.

Verified: gl_api.ludic and gl_thunks.ll regenerate byte-identically, ludic-dev
test 135/135, selfhost-test 32/32, and headless gl_triangle on an RTX 3070 Ti
matches the macOS frame to within one level per channel.
