Shokunin f69ce834eb Frame generation on the render thread from recorded draw lists

[video] frame_generation (opt-in, with render_thread): the render thread keeps
each game frame's replayed draw list, matches the triangles of the last two
(frame_gen.c), and presents in-between frames at the display refresh by
redrawing the newer list into separate surfaces with matched vertices
interpolated. It never runs guest code. Real frames are composed at their
flip and presented after the generated ones, with the same pixels and
order. Generation uses only measured surplus: a plan from render-thread CPU,
generated-frame cost and swap time, a breaker after backpressure or late
guest frames, and a pause while dynamic resolution is over budget. The
render-thread core gains a timed tick hook. Frame-cost queries pause around
generation, so dynamic resolution measures real frames only.

Tests: frame_gen_test, render_thread_test (tick), gl_frame_gen_test (real
frames identical off/on; phase 0/1 equal the endpoints). Docs:
docs/FRAME_GENERATION.md.
