Move the display type/property from config into mode.

[andy840119]

Inspired from #2176

Maybe it's possible to make a mode that:

• Able to decide lyric/romanization as main text.
• Able to decide show the top text (e.g. ruby) or bottom text (e.g. romanization or lyric text).
• Able to decide should show the translation or not. (Separated to Move the display translation/prefer language from config into mode #2198)

Maybe placed into difficulty reduction i guess?

Here's the list or pros and cons in the notion(written in chinese):

Pros:

• Will be easy to make the preset by user. They can display the lyric with romanization if they are not native speaker.
• The record will be saved in the replay.
• The logic of lyric display config can be more easy to maintain.

Cons:

• Might be better to think about other related options before doing this?
• Need to apply the mode every time if need this feature.
• It might be weird that translation not become a mod also. Discussion is in the Move the display translation/prefer language from config into mode #2198
