GameFileCache: Pass std::function by reference rather than by value

Browse source 
std::function is internally allowed to allocate, and these functions
aren't being stored anywhere (only called), so we can freely get rid
of some minor overhead here by passing by reference.

This change also creates aliases for the functions, so that there isn't
a lot of visual noise when reading the function signatures.
