Adds tools/symbolize_crash.cpp, built alongside the game as a console exe:
it reads a crash_report_*.txt written by writeExceptionBacktrace and prints
the backtrace with function names, source lines and inlined frames, in call
order, coloured when standard output is a console.
Symbols come from DbgHelp against the build's PDB rather than an external
symbolizer. SymLoadModuleEx takes the runtime base out of the report's
module table, so the relocation arithmetic /DYNAMICBASE forces on us is
DbgHelp's problem now; a report predating the module table loads at the
image's preferred base, which is where it ran. Verified under Wine: PDB
line info and inline traces both resolve.
The tool wants C++23 (std::print, std::format) where the game is C++17, so
the standard is set on the target alone. Both MSVC 19.51 and clang-cl build
it clean in all three configurations.
