Add more usable osu!mania touch input system

[peppy]

This takes smoogi's previous effort (#27790) and presents it in a state where it can be merged without skin configurability concerns. I've left the configurable settings in code for exposing in the future.

I've made changes to bring it more in line with how taiko's touch area system was implemented for conformity. The major change is that it no longer uses the presence of touch mod to decide whether to display (and can now be summoned using a mouse click or touch).

The drawable implementation here is copied verbatim. I'd probably make some visual touches but I don't want to dwell on this and would love to get this functional improvement in the next release to help the seemingly large number of osu!mania mobile lazer players.

If this is a thing, should we revert #25336 / #25777 while we're at it?

This is very uncomfortable for players who originally play like Melody or Kalpa

I found a work around...

1. Use a skin with really large column widths (or modify one... I modified the Mobile Mania skin)
2. Use the Horizontal scale setting (use the Gameplay scale mode) to adjust the skin's width to align with the touch area buttons

and now it feels somewhat like a regular mobile rhythm game!
