ab6394d2 - [lldb] Bring Debuginfod's StreamedHTTPResponseHandler to SymbolLocatorSymStore (#187687)

[lldb] Bring Debuginfod's StreamedHTTPResponseHandler to SymbolLocatorSymStore (#187687) SymbolLocatorSymStore used a simple local implementation of HTTPResponseHandler so far. That was fine for basic usage, but it would cause issues down the line. This patch hoists the StreamedHTTPResponseHandler class from libDebuginfod to SupportHTTP and integrates it in SymbolLocatorSymStore. PDB file downloads will now be buffered on disk, which is necessary since they can be huge. We use the opportunity an stop logging 404 responses (file not found on server) and print warnings for all other erroneous HTTP responses. It was more complicated before, because the old response handler created the underlying file in any case. The new one does that only once the first content package comes in.
