Add filename / line number to stack traces on Windows.

[bmahler]

Currently the glog stack trace facilities on Windows do not include file name and line number information (nor does the code for Linux as far as I can tell).

It's possible to retrieve file name and line number information using the following:

// Include SYMOPT_LOAD_LINES in SymSetOptions:
SymSetOptions(... | SYMOPT_LOAD_LINES);

...

// Later, when calling SymFromAddr, also call SymGetLineFromAddr64:
DWORD lineDisplacement = 0;
IMAGEHLP_LINE64 line = {};
line.SizeOfStruct = sizeof(IMAGEHLP_LINE64);

BOOL lineFound = SymGetLineFromAddr64(
    GetCurrentProcess(),
    reinterpret_cast<DWORD64>(pc),
    &lineDisplacement,
    &line);

I was able to use this to dump file names and line numbers:

Including these would helpful for debugging!
