Projectkk2glider/simu tmp sd path (#4231)

* Re #4224: Introduced settingsPath and use std::string for paths in simpgmspace.

* Re #4224: Relevant parts of simpgmspace.cpp moved into simufatfs.cpp and simudisk.cpp

* Removed "/" from "mask_monitor_logsw.png"

* Re #4224: findTrueFileName() refactoring

* Faster gtests (less waiting for eeprom operations to finish)

* Re #4224: Radio settings and models directories now taken from alternate path (if set) [simu]

* Fixes #3322: together with previous changes to the SD browser this prevents the simulator from browsing higher than SD card root path.

* f_chdir() debug traces
