[video_core/engines/maxwell3d] memory inline DrawState to reduce indirection on hot paths (#3758 )

usual indirection removal
helps very slightly to codegen

the idea is basically to reduce the amount of pointer deference overall in the code, and use idiomatic std::variant<>-isms to not rely on vtables/unique_ptr overhead
this should allow the compiler to emit better code
of course it's a tiny optimisation and only CPU side, but allows us to reduce indirection which is almost always a good thing

"but youre passing more parameters to the function!!!" its literally memoized into a register my friend
