Work on Monitor_FlashSectorMap

[nfbot]

From nf-interpreter created by josesimoes : nanoframework/nf-interpreter#382

nanoBooter is not being able to report the Flash map because the code in the command is commented in WireProtocol_MonitorCommands.c.

Uncomment and follow the implementation of CLR_DBG_Debugger::Monitor_FlashSectorMap to make it work

[networkfusion]

Also BlockStorageDevice requires #include <nanoPAL_BlockStorage.h>

still fails at const DeviceBlockInfo* deviceInfo = device->GetDeviceInfo(device); though which has lots of FixMe comments in block storage...

I think that it is a remnant of NETMF code and that the code indeed needs some tweaking in this section to be able to work with nf.
