Fix config write (#13503)

Browse source 
* Config - add error checking into config_streamer.c,

CONFIG_STREAMER_BUFFER_SIZE does not match actually writen data in
some cases

* Config - fix buffer read ovefrflow

CONFIG_IN_RAM and CONFIG_IN_SDCARD used 4 byte byffer, but 32 bytes
got actually copied
CONFIG_IN_MEMORY_MAPPED_FLASH used 8byte buffer, but  but 32 bytes
got actually copied

* Config - add write functions into header
