Stacktrace with backtrace to display files and lines

[guilhermelawless]

Detailed information in https://www.boost.org/doc/libs/develop/doc/html/stacktrace/configuration_and_build.html

The BOOST_STACKTRACE_USE_BACKTRACE option was the only reliable one here, but should be tested across a variety of configurations if possible. There is a callout for clang but setting a custom path for the file is not supported here - haven't tested with clang.

• Adds NANO_STACKTRACE_BACKTRACE cmake option. If enabled, will link against libbacktrace and define the BOOST_STACKTRACE_USE_BACKTRACE macro where necessary, except on Windows which already has good default stacktrace
• Adds --debug_stacktrace CLI option to easily see what will be the usual stacktrace

Example output:

nano_node --debug_stacktrace
 0# main at /home/glawless/nano_ws/nano-node/nano/nano_node/entry.cpp:1087
 1# __libc_start_main in /lib/x86_64-linux-gnu/libc.so.6
 2# _start in ./nano_node

On macOS/clang/libstd++, I did get the issue of not finding backtrace.h mentioned in https://www.boost.org/doc/libs/develop/doc/html/stacktrace/configuration_and_build.html#stacktrace.configuration_and_build.f3

But I think that's fine since this is opt-in and there are known workarounds.
