rework hardware and C library settings

Make the menu system for configuration more intuitive.

First choose operating system, then hardware, starting with architecture.
Then choose either generic or a sample system. When choosing a sample be more strict
in case of MMU or Endianess selection, so a misconfiguration isn't possible.

Furthermore put a new top level menu for C library configuration and
add Binary format, Instruction set, version selection, float type and
any C library specific options.

Refactor the duplicate definition of Qemu system versatile and Synopsys NSIM.
