Use a macro to compute the size of arrays at compile time (#18044) 
* Add ARRAY_SIZE and CEILING utility macros

* Apply a coccinelle patch to use ARRAY_SIZE

* fix up some straggling items

* Fix 'make test:secure'

* Enhance ARRAY_SIZE macro to reject acting on pointers

The previous definition would not produce a diagnostic for
```
int *p;
size_t num_elem = ARRAY_SIZE(p)
```
but the new one will.

* explicitly get definition of ARRAY_SIZE

* Convert to ARRAY_SIZE when const is involved

The following spatch finds additional instances where the array is
const and the division is by the size of the type, not the size of
the first element:
```
@ rule5a using "empty.iso" @
type T;
const T[] E;
@@

- (sizeof(E)/sizeof(T))
+ ARRAY_SIZE(E)

@ rule6a using "empty.iso" @
type T;
const T[] E;
@@

- sizeof(E)/sizeof(T)
+ ARRAY_SIZE(E)
```

* New instances of ARRAY_SIZE added since initial spatch run

* Use `ARRAY_SIZE` in docs (found by grep)

* Manually use ARRAY_SIZE

hs_set is expected to be the same size as uint16_t, though it's made
of two 8-bit integers

* Just like char, sizeof(uint8_t) is guaranteed to be 1

This is at least true on any plausible system where qmk is actually used.

Per my understanding it's universally true, assuming that uint8_t exists:
https://stackoverflow.com/questions/48655310/can-i-assume-that-sizeofuint8-t-1

* Run qmk-format on core C files touched in this branch

// late Jan 2020, got Ohkeycaps Dactyl Manuform 5x6
// https://play.typeracer.com shows about 75-80wpm (en) or ~400cpm (de) on my classic keeb.
// Never did proper touch typing, basically didn't use ring finger much, mostly index/middle and pinky (only to hold down modifiers, really).
// Feb 2020, switching to Colemak DH after 30 years of Qwerty, uh oh...
// mid Feb, 20wpm/87% on monkeytype.com (no punct, numbers)
// early March, 28wpm/90% on MT (plus punct./numbers from here on); 25wpm on typeracer
// early April, 35wpm/92% on MT; 41wpm on typeracer
// early May, 45wpm/96% on MT; 46wpm on typeracer; my qwerty is deteriorating, I need to look at the keys more and more o_O
// early June, 49wpm/95% on MT (sigh ...); 50wpm on typeracer;
// early July, 50wpm/96% on MT (...); 52wpm/96% on typeracer;
// early August, 55wpm/96% on MT; 55wpm/98% on typeracer;
// early September, 57wpm/97% on MT; 58wpm/97% on typeracer;
// early October, 59wpm/96% on MT; 61wpm/97% on typeracer;
// November, 56wpm/97% on MT; 62wpm/98% on typeracer;
// December, 62wpm/96% on MT; 66wpm/98% on typeracer;
// January, 61wpm/97% on MT; 65wpm/98% on typeracer;
// February, 64wpm/97% on MT; 67wpm/98% on typeracer; my qwerty on the laptop is still fine, but I miss my shortcuts badly.
//
// So that's one year on Colemak. Was it worth the switch? Probably not, though
// I also had to first learn proper technique, but that was actually swift, as
// the keyboard nicely forces that on you. I really like home row mods though,
// they are so comfy. Need to rethink my combos some more, still.
