Move message_name() strings to flash via LOG_STR

Browse Source 
message_name() returned bare string literals that stayed in RAM on
ESP8266. Change return type to const LogString * and wrap with LOG_STR()
so they are stored in flash. Update log_send_message_ to use
LOG_STR_ARG() accordingly.

Also fix clang-tidy: rename append_p_esp8266_ to append_p_esp8266,
add NOLINTNEXTLINE for conditionally-unused dump_field overloads.
