With D92696, the Scudo Standalone GWP-ASan flag parsing was changed to the new GWP-ASan optional one. We do not necessarily want this, as this duplicates flag parsing code in Scudo Standalone when using the GWP-ASan integration. This CL reverts the changes within Scudo Standalone, and increases `MaxFlags` to 20 as an addionnal option got us to the current max. Differential Revision: https://reviews.llvm.org/D95542
