Andreas Kling 252cb54310 LibSymbolication+SystemMonitor+bt: Move symbolication back in-process
Process-separated symbolication was cute, but ultimately the threat
model is kinda silly. We're already *running* the binary, but we're
afraid to parse its symbol table? :^)

This commit makes SystemMonitor and bt do symbolication in-process.
SymbolServer and the symbol user will be removed separately.
