📄 Description

Set -mcpu=sandybridge to target Sandy Bridge level instruction set, which is roughly what we support for PS4 guest applications when accounting for CPU patches.
Disable AVX2 for CryptoPP for similar reasons; this needs its own flag set as the compile options we supply don't affect its try_compile support check.
Move CryptoPP to source build on Windows, so that updated flags will apply.
Minor improvement to architecture detection to account for if CMAKE_SYSTEM_PROCESSOR is missing for some reason.
