Alpine has dropped support for libexecinfo since version 3.17. This PR pulls in lf-lang/reactor-cpp#59 which makes the compilation of reactor-cpp more robust, so that it can handle if backtrace support is not available or provided by an alternative implementation. Consequently, we can remove the current workarounds in the LF code generator.

This makes the backtrace mechanism that we currently use for assertions portable. The current mechanism was implemented under the assumption, that all Linux distributions provide
execinfo.h, which is not the case (e.g. Alpine has dropped libexecinfo). This PR provides a more robust implementation that uses FindBacktrace to find the correct backtrace implementation.This change allows us to simplify the docker support in LF.
