pw_log_string: Split out the handler facade

Splits up pw_log_string to formalize the implicit facade for the
string log handler. In addition, it sets up the module so that the
mhandler can be used independently from the pw_log_string backend
for pw_log. This is useful when mixing tokenized and string based
logging on some targets.

Pigweed

Pigweed is an open source collection of embedded-targeted libraries–or as we like to call them, modules. These modules are building blocks and infrastructure that enable faster and more reliable development on small-footprint MMU-less 32-bit microcontrollers like the STMicroelectronics STM32L452 or the Nordic nRF52832.
