tools/idf_monitor: automatically decode UART core dumps

This adds detection of UART core dumps to IDF monitor. By default,
core dumps are not printed to the console, but are processed by
espcoredump.py using 'info_corefile' command. The result is printed
to stdout.

This feature can be disabled in menuconfig.

In the future this can be extended to allow running espcoredump.py
with 'dbg_corefile' argument, which is similar to the current GDB Stub
behavior.

Related to IDF-52.
