scipoptsuite: init at 9.2.0

[FettGoenner]

Packaged all packages included in the SCIP Optimization Suite,
an open-source toolbox for generating and solving mixed integer nonlinear programs.

I did not actually make scipoptsuite an actual package, just its parts. (If the MR is confusing.)

Including these packages gives computer scientists, applied mathematicians and enthusiasts quick and easy access to this actively developed optimization suite.

Renamed preexisting package soplex to scipopt-soplex to fit the SCIP Optimization Suite package names and added additional necessary build inputs to it.

Added packages:

• scipopt-scip
• scipopt-zimpl
• scipopt-papilo
• scipopt-gcg
• scipopt-ug

And I referenced myself as the maintainer.
