Attempt to use a prefix hook in EFL

[EvelynTSMG]

it would be a significant optimization to prefix-hook the method, allocate our own handle container struct, and hook the/any method which frees such structure (because the game cannot free what we have allocated, and vice versa)

right now the game proceeds with a complete VBF load and then we perform an additional load with EFL if required, which is correct but not ideal.
