fix(input): Key.Up/Down/Left/Right are the held set's 128-131

Browse source 
The arrow Key constants folded to the codes of w/s/a/d, which is what the
per-frame key reports for an arrow, but cocoa.ll has always stored an arrow in
the held-key set under 128-131. So Input.key_down(Key.Up) read the W bit and
Input.move_i's arrow half never moved anything. Input.key keeps its WASD alias,
so games comparing it with 'w' (snake, chronorift) still take the arrows.

New example input_arrows.ludic, checked by ludic-dev test.

**Held arrow keys register** — `Key.Up`, `Key.Down`, `Key.Left` and `Key.Right` are 128-131.
They folded to the codes of w, s, a and d, which is what the single per-frame key
(`Input.key`) reports for an arrow. The held-key set has always stored an arrow under
128-131, so `Input.key_down(Key.Up)` tested the W bit and `Input.move_i`'s arrow half never
moved anything. `Input.key` keeps its WASD alias: a game comparing it with `'w'` still
takes the arrows.
