[hle] inline HLE cmif request to not allocate on heap stuff (#3605)

Browse source 
so basically each construction of HLEContext and whatever would result in a heap allocation (atleast 1)

so what if instead of that we did a memset() at ctor time and we avoided heap allocations altogether?

reminder that std::vector<> CAN do small object optimisation but it's not guaranteed
