accounts-db: fix 8G+ memory spike during hash calculation (anza-xyz#1308)

We were accidentally doing several thousands 4MB allocations - even
during incremental hash - which added up to a 8G+ memory spikes over ~2s
every ~30s.

Fix by using Vec::new() in the identity function. Empirically 98%+
reduces join arrays with less than 128 elements, and only the last few
reduces join large vecs. Because realloc does exponential growth we
don't see pathological reallocation but reduces do at most one realloc
(and often 0 because of exp growth).
