Subject: [PATCH] yuzu/main: Move functions stored into static std::function
 instances out of OnGameListDumpRomFS()

This can cause warnings about static constructors, and is also not ideal
performance-wise due to the indirection through std::function. This also
keeps the behavior itself separate from the surrounding code, which can
make it nicer to read, due to the size of the code.
