Closes #10612. Some of the code is taken from there, some other from JochenKalmbach/StackWalker.

• Uses the StackWalk64 API. Column numbers are omitted because DbgHelp doesn't seem to expose it, short of parsing the PDB ourselves (apparently it is also problematic for most Windows tools, including the Visual Studio debugger).
• Always generates a PDB file unless --no-debug is specified. Also no longer emits DWARF debug information on Windows.
• Renames the environment variable CRYSTAL_LOAD_DWARF to CRYSTAL_LOAD_DEBUG_INFO to be platform-independent.

Note that this doesn't catch access violation (0xC0000005) and stack overflow (0xC00000FD) yet.
