drsyms: honor mangling flags to query routines on Windows

We decided that always requesting mangled symbols by turning off SYMOPT_UNDNAME was too much of a performance loss to support, and had major complications with respect to public and private symbols (issue #558). Instead, we chose to ignore the mangling flags for simplicity and performance and just get the default demangled symbols on Windows. This issue covers adding support to honor the mangling flags so that users can get fully mangled names and fully demangled names (most importantly, ones with parameter types).

*** TODO add issue #601 workaround: global flag DRSYM_DEMANGLE_FULL so symquery can have template and func params?

No, it doesn't work that way: up front it's either SYMOPT_UNDNAME or
nothing. So either mangled, or partially demangled. To get full
demangling, you'd have to start mangled and call the undecorate routine
every time. So probably not worth adding this global flag? Or might some
user want to pay the perf cost of always starting with mangled symbols?
