[Docs] RGB Animation documentation on reducing memory footprint (#5813)

Browse Source 
* Improve Animation docs with example

 - example to reduce flash footprint of animations using RGBLIGHT_EFFECT_ defines

* Re-order the effects list

* Update docs/feature_rgblight.md

* Introduce line breaks

* Add title for animation speed section

* Organize Animation Defines Into Groups

* Use the RGB EFFECT recommended by mtei in docs

 - has the most modes, and STATIC_LIGHT can't really be disabled.

* Use more accurate titles for effects and animation

 - accidentally put a toggle in settings

if `RGBLIGHT_EFFECT_xxxx` or `RGBLIGHT_ANIMATIONS` is defined, you also have a number of animation modes at your disposal:

The following options can be used to tweak the various animations:
### Effect and Animation Toggles
Use these defines to add or remove animations from the firmware. When you are running low on flash space, it can be helpful to disable animations you are not using.

### Example Usage to Reduce Memory Footprint
1. Remove `RGBLIGHT_ANIMATIONS` from `config.h`.
1. Selectively add the animations you want to enable. The following would enable two animations and save about 4KiB:
```diff
#undef RGBLED_NUM
-#define RGBLIGHT_ANIMATIONS
+#define RGBLIGHT_EFFECT_STATIC_GRADIENT
+#define RGBLIGHT_EFFECT_RAINBOW_SWIRL
#define RGBLED_NUM 12
#define RGBLIGHT_HUE_STEP 8
#define RGBLIGHT_SAT_STEP 8
```
### Animation Speed
You can also modify the speeds that the different modes animate at:
