Using commands structure in the lazer storybook for the lyric layout.

[andy840119]

The idea is from https://github.com/ppy/osu/pull/27539/files

We define something like Class stage or Preview stage, for able to generate the general transform actions.
And the final goal is to let user able to edit the lyric appear/disappear timing, position, anchor and transformations.

Maybe it's OK to use the same structure how storybook is using?
