Make emojier use its own data instead of relying on ibus.

1. IBus data originated from unicode official data, use unicode data
   reduce the dependency on emoji feature.
2. It's not build data from run time gives us more control on when to
   update the data. Especially if font does not cover the emoji, it will
   just display a blank space. (At this point unicode-emoji 15.0 is out,
   but noto doesn't fully support it yet).
3. It is never a part of kimpanel infra, so also move it out of kimpanel
   directory.

There are also other some small improvements:
1. The category name string is now under our own control, this also
   fixes the "&" accelerator issue in the side bar.
2. dict loading order now always load en. Otherwise certain language may
   only shows a small number of emoji. Can be tested via
   `LANGUAGE=ti_ER LANG=ti_ER.UTF-8 plasma-emojier`
