Improve consistency in UNICODEMAP code and docs, update docs/understanding_qmk (#4774)

Browse Source 
* Remove unused UNICODE(n) macro, update docs

* Add note about max length of unicode_map to docs

* QK_UNICODE_MAP → QK_UNICODEMAP

* Refactor process_unicode_map

* process_unicode_map → process_unicodemap

This is done for consistency: UNICODEMAP is the method (hence UNICODEMAP_ENABLE, process_unicodemap), whereas unicode_map is the mapping table itself.

* Update references and ordering in docs/understanding_qmk

* Add additional note to docs/understanding_qmk

* &unicode_map[index] → unicode_map + index

This avoids the issue of the compiler sometimes complaining about the array index being out of range

* Update docs/getting_started_make_guide

* Update method sections in docs/feature_unicode

There are three Unicode keymap definition methods available in QMK: There are three Unicode keymap definition methods available in QMK:
## UNICODE_ENABLE ## `UNICODE_ENABLE`
Supports Unicode up to `0xFFFF`. The keycode function is `UC(n)` in the keymap file, where _n_ is a 4 digit hexadecimal number. Supports Unicode up to `0x7FFF`. This covers characters for most modern languages, as well as symbols, but it doesn't cover emoji. The keycode function is `UC(c)` in the keymap file, where _c_ is the code point's number (preferably hexadecimal, up to 4 digits long). For example: `UC(0x45B)`, `UC(0x30C4)`.
## UNICODEMAP_ENABLE ## `UNICODEMAP_ENABLE`
Supports Unicode up to `0x10FFFF` (all possible code points). You need to maintain a separate mapping table `const uint32_t PROGMEM unicode_map[] = {...}` in your keymap file. The keycode function is `X(n)`, where _n_ is an array index into the mapping table. Supports Unicode up to `0x10FFFF` (all possible code points). You need to maintain a separate mapping table `const uint32_t PROGMEM unicode_map[] = {...}` in your keymap file. The keycode function is `X(i)`, where _i_ is an array index into the mapping table. The table may contain at most 1024 entries.
And you may want to have an enum to make reference easier. So you'd want to add something like this to your keymap: You may want to have an enum to make referencing easier. So, you could add something like this to your keymap file:

Make sure that the order for both matches. Then you can use `X(BANG)` etc. in your keymap.
## UCIS_ENABLE ## `UCIS_ENABLE`
Supports Unicode up to `0x10FFFF` (all possible code points). As with `UNICODEMAP`, you may want to maintain a mapping table in your keymap file. However, there are no built-in keycodes for this feature — you will have to add a keycode or function that calls `qk_ucis_start()`. Once it's been called, you can type the mnemonic for your character, then hit Space or Enter to complete it or Esc to cancel. If the mnemonic matches an entry in your table, the typed text will automatically be erased and the corresponding Unicode sequence inserted.

Once this function's been called, you can type the corresponding mnemonic for your character, then hit Space or Enter to complete it, or Esc to cancel. If the mnemonic matches an entry in your table, the typed text will automatically be erased and the corresponding Unicode character inserted.
For instance, you would need to have a table like this in your keymap: For instance, you would define a table like this in your keymap file:
```c ```c
const qk_ucis_symbol_t ucis_symbol_table[] = UCIS_TABLE const qk_ucis_symbol_t ucis_symbol_table[] = UCIS_TABLE(
( UCIS_SYM("poop", 0x1F4A9), // 💩
UCIS_SYM("poop", 0x1f4a9), UCIS_SYM("rofl", 0x1F923), // 🤣
UCIS_SYM("rofl", 0x1f923), UCIS_SYM("kiss", 0x1F619) // 😙
UCIS_SYM("kiss", 0x1f619)
); );
``` ```
You run the function, and then type "rofl" and hit enter, it should backspace remove "rofl" and input the `0x1f923` unicode. You call `qk_ucis_start()`, then type "rofl" and hit Enter. QMK should erase the "rofl" text and input the laughing emoji.
### Customization ### Customization
There are several functions that you can add to your keymap to customize the functionality of this feature. There are several functions that you can define in your keymap to customize the functionality of this feature.
* `void qk_ucis_start_user(void)` - This runs when you run the "start" function, and can be used to provide feedback. By default, it types out a keyboard emoji. * `void qk_ucis_start_user(void)` – This runs when you call the "start" function, and can be used to provide feedback. By default, it types out a keyboard emoji.
* `void qk_ucis_success(uint8_t symbol_index)` - This runs when the unicode input has matched something, and has completed. Default doesn't do anything. * `void qk_ucis_success(uint8_t symbol_index)` – This runs when the input has matched something and has completed. By default, it doesn't do anything.
* `void qk_ucis_symbol_fallback (void)` - This runs if the input text doesn't match anything. The default function falls back to trying that input as a unicode code. * `void qk_ucis_symbol_fallback (void)` – This runs when the input doesn't match anything. By default, it falls back to trying that input as a Unicode code.
