BareMetal: Get rid of unused GdbServerProviderProcess class

We don't need in this class, because the remote GDB servers are
launches by the RunWorker.

Besides, the BareMetalDevice::canCreateProcess() and the
BareMetalDevice::createProcess() are not even gets called at all.

Tested with the STM32 Nucleo-F767ZI board using the ST-Util GDB provider.
