Add support for more than 2 arguments to minOf/maxOf (both for XInt/YInt, XAxisSolver/YAxisSolver variants)

[dimsuz]

It is not the first time I have this usecase, where I want more than two arguments for minOf.

minOf currently supports XInt/YInt and XAxisSolver/YAxisSolver (but only 2 args for both kinds)...

I have just ran into another case with the latter. The layout is like this:

TITLE
PRIMARY_ACTION (optional, maybe GONE)
SECONDARY_ACTION (optional, maybe GONE)
---screen-bottom---

I want to do something like this:

titleView.layoutBy(
  x = matchParentX(),
  y = minOf(
     bottomTo { primaryAction.top() - 16.ydip },
     bottomTo { secondaryAction.top() - 16.ydip },
     bottomTo { parent.bottom() - 16.ydip },
  )
)

but minOf has only 2 args... Similar situation is for xint/yint, I often find myself wishing for more args.

Is this possible or maybe I also miss some easy workaround to achive what I want? I know I can put if (someView.isVisible) rule1 else rule2 in my lambdas, but that looks not very elegant and a bit messy...

P.S. Can't help but think that if we'd be in the functional programming land, XInt/Yint, and axis solvers could be an instance of Monoid + Ord and all the stdlib functions (including min) would just work on them. But oh well :)

This should be pretty doable.
