Implement a pool in FMT to avoid allocating heap memory when passing a char* to the backend, usually when formatting a %s argument.

Previously since a char* can have any length, this was managed by FMT by converting it into a std::string.
Now we store it into a configurable size node that can store a fixed size string, otherwise it falls back to std::string.

pdcp,rlc: increase number of PDCP SDUs for notification from RLC
...
the current value of 256 limits the number of PDCP SDUs that can be
notified from RLC. The limit is quickly hit when too many SDUs
are in flight. This can cause unwanted log entries and weird PDCP
behaviour.
the patch increases the value to 1024, which still can be too few if
many smaller SDUs are traveling.
The patch also set the log level to warning to quicker spot
misconfigs in logs.
Fixes #2616
