[*] change all std::unordered_map and std::unordered_set into ankerl::unordered_dense::map/set variants (#3442)

mainly doing this to reduce memory footprint; we all know how nice ankerl::unordered_dense is

in theory 4x faster - in practice these maps arent that "hot" anyways so not likely to have much perf gained

i just want to reduce mem fragmentation to ease my porting process, plus it helps other platforms as well (ahem weak Mediatek devices) :)
