Refactor rgblight_reconfig.h (#7773)

* Moved contents of rgblight_reconfig.h to rgblight_post_config.h.

In #3582, rgblight_reconfig.h had to be newly created. Now, the build system of qmk_firmware has a post_cofig feature, so that what was done in rgblight_reconfig.h can now be realized in rgblight_post_config.h.

**This commit does not change the build result.**

Testing script
```shell
  # build on master
  git checkout master
  echo master > /tmp/master_md5.txt

  # RGBLIGHT_ENABLE = no
  make HELIX=verbose helix/rev2:default:clean
  make HELIX=verbose helix/rev2:default
  md5 helix_rev2_default.hex >> /tmp/master_md5.txt

  # RGBLIGHT_ENABLE = yes, with animations
  make HELIX=verbose helix/rev2/back:default:clean
  make HELIX=verbose helix/rev2/back:default
  md5 helix_rev2_back_default.hex >> /tmp/master_md5.txt

  # RGBLIGHT_ENABLE = yes, without animations
  make HELIX=verbose,no_ani helix/rev2/back:default:clean
  make HELIX=verbose,no_ani helix/rev2/back:default
  md5 helix_rev2_back_default.hex >> /tmp/master_md5.txt

  # build on refactor_rgblight_reconfig.h
  git checkout refactor_rgblight_reconfig.h
  echo refactor_rgblight_reconfig.h > /tmp/branch_md5.txt

  # RGBLIGHT_ENABLE = no
  make HELIX=verbose helix/rev2:default:clean
  make HELIX=verbose helix/rev2:default
  md5 helix_rev2_default.hex >> /tmp/branch_md5.txt

  # RGBLIGHT_ENABLE = yes, with animations
  make HELIX=verbose helix/rev2/back:default:clean
  make HELIX=verbose helix/rev2/back:default
  md5 helix_rev2_back_default.hex >> /tmp/branch_md5.txt

  # RGBLIGHT_ENABLE = yes, without animations
  make HELIX=verbose,no_ani helix/rev2/back:default:clean
  make HELIX=verbose,no_ani helix/rev2/back:default
  md5 helix_rev2_back_default.hex >> /tmp/branch_md5.txt

  diff -u /tmp/master_md5.txt /tmp/branch_md5.txt
```

* Expressions that are too long are difficult to read, so wrap them.

* Edit the expression again

* remove `defined(RGBLIGHT_ANIMATIONS)` in `tmk_core/common/*/suspend.c`, `tmk_core/protocol/*/main.c`

move contents of rgblight_reconfig.h to rgblight.h.

The following changes were made to rgblight.h.

```diff
+#ifdef RGBLIGHT_USE_TIMER
 void rgblight_task(void);

```

The following changes were made to tmk_core/common/avr/suspend.c, tmk_core/common/chibios/suspend.c, tmk_core/protocol/chibios/main.c, tmk_core/protocol/lufa/lufa.c, tmk_core/protocol/vusb/main.c.

```
```diff
-#if defined(RGBLIGHT_ANIMATIONS) && defined(RGBLIGHT_ENABLE)
+#if defined(RGBLIGHT_ENABLE)
         rgblight_task();

```

* remove 'defined(RGBLIGHT_ANIMATIONS)' in tmk_core/common/keyboard.c
