agra b3558c3274 ffi 1.31: uikit_scene_will_connect_ios via #objc_call ...

The biggest Phase 1D cluster: the iOS scene-lifecycle entry that runs
at every launch. UIWindow alloc/init, UIViewController alloc/init, GL
view alloc/init/install, root-view-controller wiring, layer access +
setOpaque:, EAGL drawable-properties dictionary build,
screen/nativeScale DPI scaling, makeKeyAndVisible, UITextField subview
install, CADisplayLink construct + addToRunLoop. Every return shape
this file uses (void, *void, f64) and every arg shape (BOOL via `xx
0`/`xx 1`, multi-arg selectors `displayLinkWithTarget:selector:` and
`setObject:forKey:`) is exercised by this single launch.

Net -44 lines on this commit (104 → 60). Also drops a stale
`EAGLContext := objc_getClass(...)` decl that wasn't referenced inside
this function — EAGL context creation lives in uikit_create_gl_context
(already migrated in 1.29). uikit.sx is now 868 lines (-69 cumulative
across Phase 1D).

iOS-sim chess regression smoke: app launches cleanly, board renders
with status-bar clearance, sharp DPI scaling, compositor working,
display-link tick driving frames. Every part of the migrated function
is on the launch path and all of it succeeds.
