Thomas Martitz 287454de2e Hosted/linux: Add process/cpu info screen to the debug menu.
The new menu is very helpful on RaaA, but also shown in the sim. It shows
the process cpu usage, process' time stats (user,sys,real) and the cpu
frequency stats.

It uses a thread to sample the data, however the thread is not created
until the menu is visited for the first time.
