> Copy asan_rtl.* and agent_logger.exe to the syzygy directory for the ASan builds.
> 
> Currently the syzygy_optimize script was taking care of copying asan_rtl.[dll|pdb] to the syzygy directory, this was causing 2 warnings when building a SyzyASan splitted build with ninja:
> 
> - ninja: warning: multiple rules generate syzygy\asan_rtl.dll. builds involving this target will not be correct; continuing anyway
> - ninja: warning: multiple rules generate syzygy\asan_rtl.dll.pdb. builds involving this target will not be correct; continuing anyway
> 
> The multiple rules come from the fact that both syzygy\chrome.dll and syzygy\chrome_child.dll were trying to generate those artifacts.
> 
> I've also added agent_logger.exe to the syzygy directory, with this it'll be easier for the person grabing a SyzyASan build from the LKGR builder to use it.
> 
> I've also removed all the "--agent-dll" logic from syzygy_instrument.py as it was only copying the asan binaries to the syzygy directory, it's now done directly in the 'copy_syzyasan_binaries' gyp target.
