[video_core] fix redundant resize-copy overload and just use default-init resize, to reduce stutter on Mario BP (#3874)

before vs. after

Mario Brothership kept remaking vectors of sizes 256 AND 4095 (TIC) and 1215 AND 524287 (TSC) every single frame, which resulted in a noticeable overhead

the main cause was because of using `resize(n, c)` instead of `resize(n)` (also to aggressively resize for more room beforehand), the copy overload of resize does a copy of... well.. the value over the entire vector, additionally __append() keeps getting called because the capacity goes bonkers and all over the place
