[nrfconnect] Moved FlashHandler implementation to separate file (proj…

…ect-chip#23570) The FlashHandler implementation was coupled with Matter OTAImageProcessorImpl, what resulted with the fact that it was not possible to use build other DFU mechanisms, like DFU over BT SMP without Matter OTA enabled. Summary of changes: * Moved FlashHandler to separate file called ExternalFlashManager * Added ifdefs to OTAUtil that prevents from building Matter OTA dependencies while Matter OTA is disabled.
