allow customizing decrease delay of rgb heatmap (#11322)

* allow customizing decrease delay of rgb heatmap

* rename rgb typing heatmap decrease delay variable

* address review comments

* nix-shell: add clang-tools required for formatting the C code

* heatmap: use real timer to track decrement rate

* heatmap: fix ifndef var name typo

* heatmap: add docs

* Update docs/feature_rgb_matrix.md

### RGB Matrix Effect Typing Heatmap :id=rgb-matrix-effect-typing-heatmap
This effect will color the RGB matrix according to a heatmap of recently pressed
keys. Whenever a key is pressed its "temperature" increases as well as that of
its neighboring keys. The temperature of each key is then decreased
automatically every 25 milliseconds by default.
In order to change the delay of temperature decrease define
`RGB_MATRIX_TYPING_HEATMAP_DECREASE_DELAY_MS`:
```c
#define RGB_MATRIX_TYPING_HEATMAP_DECREASE_DELAY_MS 50
```
