Issue

With #3606, there is a dramatic performance increase when reading/writing lots of NCA files, but most of the performance improvement is from OpenSSL responding significantly better to CPU optimizations than MbedTLS.

To leverage this, we should add support for building OpenSSL directly, rather than on CI. This means that, e.g. the Zen 4 builds should see this big jump in R/W performance.

On that topic, we may as well begin providing optimized builds in MinGW land.
