Reduce example application memory usage



Our currently supported targets DISCO_L072CZ_LRWAN1 and MTB_MURATA_ABZ

only have 20kB of RAM which requires some memory usage optimizations

to LoRa example application especially when compiled with GCC compiler.



This commit reduces application tx and rx buffers to 30 bytes (instead of

255) as application only sends short messages.



Also main thread stack size is reduced to 1024 bytes for these two targets.

NOTE! Due to small stack size, mbed traces cannot be enabled for these targets!
