feat: every key on the keyboard is bindable - the F-row, the six-pack, Caps Lock and the numpad

Browse source 
The platform gave these keys no code at all, so a game's rebinding screen could not take
one and nothing said why. Windows asked the active layout what they type and got nothing
(w_vk_char answers 0 for a key with no character); macOS let them fall through to
charactersIgnoringModifiers, which reports NSF1FunctionKey and its neighbours at 0xF704
and up - outside the 256-bit held set either way.

w_keyval and ev_keyval now name them, with the same codes on both: 132-143 F1-F12,
144-149 Home / End / PageUp / PageDown / Insert / Delete, 150 Caps Lock, 152-161 the
numpad digits, 162-166 its * + - . and /. The numpad's Enter is Enter.

Key.F1, Key.Home, Key.Numpad0 and the rest fold at compile time, and Input.key_label
names them without asking the layout - a key that types nothing is called the same thing
on every layout.

examples/library/input_typeless_keys.ludic covers the codes, the names, the held set and
the press edge; 150 passed in ludic-dev test, 33 in selfhost-test.

bump: minor
type: feat
**Every key on the keyboard is bindable** — the F-row, Home/End/PageUp/PageDown,
Insert/Delete, Caps Lock and the numpad reach a game as codes 132-166.
Until now the platform gave them no code at all, so a game's rebinding screen could
not take one and nothing said why. Windows asked the active layout what they type and
got nothing back (`w_vk_char` answers 0 for a key with no character); macOS let them
fall through to `charactersIgnoringModifiers`, which reports `NSF1FunctionKey` and its
neighbours at 0xF704 and up - outside the 256-bit held set either way.
- **The codes are the same on both platforms**: 132-143 are F1-F12, 144-149 are Home,
End, PageUp, PageDown, Insert and Delete, 150 is Caps Lock, 152-161 are the numpad
digits and 162-166 its `*`, `+`, `-`, `.` and `/`. The numpad's Enter is Enter.
- **`Key.F1`, `Key.Home`, `Key.Numpad0`** and the rest fold at compile time like the
other named keys.
- **`Input.key_label`** names them - "F1", "Home", "CapsLock", "Num 0", "Num /" - and
does *not* ask the layout, because a key that types nothing is called the same thing
on every layout.
