Add ability to make cursor show even during touch input

[peppy]

I completely disagree with this from a UX perspective, but it's come up so often that I figure we should just let users bone themselves.

Main change is in ee0c67e. Cleanup pass in ef10145, including renaming MenuCursorContainer to make its purpose more understandable.

I haven't tested on a touch device, but it should work. Will test later today when I have access to one, if no one beats me.

Touch:

• Closes Gameplay cursor still appears in a faded state while touch input is received #14434
• Closes (Android) Pen pressure causes cursor to dissappear #10228
• Addresses Option to Show Cursor during Gameplay for Android #14427 / Display gameplay cursor when playing on touchscreen with stylus #19331
• Works around current regression with some tablets that are exposing as touch events (fix via Fix Windows Ink events being handled as touch events osu-framework#5309 may take some time due to SDL deps.) ie. Osu with external tablet software not working propertly #19245 / Dragging on tablet hides cursor and acts as touch input #19150 / Game cursor disappearing when dragging on tablet #19337

Is there an issue to reference here for discussion/where discussion has taken place?

• Osu with external tablet software not working propertly #19245
• Dragging on tablet hides cursor and acts as touch input #19150
• Game cursor disappearing when dragging on tablet #19337

I think this is fine for the time being.
