This seems ok to remove the build flag.
Should we also contemplate changing WebsiteDataStoreConfiguration::m_networkCacheSpeculativeValidationEnabled value, or in a separate patch maybe?

I think this may be the best way to do it. Just removing the build flag will fail for platforms not building with speculative load. And just replacing the s-w-r build flag with speculative load build flag would probably be confusing.
