Summary:
PE files are stripped by default, and only contain the names of exported
symbols.
The actual reason that we bother to do this override by default is
actually due to a quirk of the way -gline-tables-only is implemented, so
I phrased the check as "if we are symbolizing from dwarf, do the symtab
override".
This fixes lots of Windows ASan tests that I broke in r250582.

Summary:
This is mostly NFC. It is a first step in cleaning up LLVMSymbolize
library. It removes "ModuleInfo" class which bundles together ObjectFile
and its debug info context in favor of:
* abstract SymbolizableModule in public headers;
* SymbolizableObjectFile subclass in implementation.
Additionally, SymbolizableObjectFile is now created via factory, so we
can properly detect object parsing error at this stage instead of keeping
the broken half-parsed object. As a next step, we would be able to
propagate the error all the way back to the library user.
Further improvements might include:
* factoring out the logic of finding appropriate file with debug info
for a given object file, and caching all parsed object files into a
separate class [A].
* factoring out DILineInfo rendering [B].
This would make what is now a heavyweight "LLVMSymbolizer" a relatively
straightforward class, that calls into [A] to turn filepath into a
SymbolizableModule, delegates actual symbolization to concrete SymbolizableModule
implementation, and lets [C] render the result.
