Summary
This patch aims at saving crash sysloging into a mtd device.
To do so, a new lib_mtdoutstream is added, which can be used in interrupt context.
Then a new syslog channel utilizing the lib_mtdoutstream is added. The channel is enabled for syslog output only when asserting.
This is useful when only a rather small flash can be used to save crash information.
Impact
syslog output when crashing.
Testing
Tested on ESP32C3.
