mean.m: Accept large DIM inputs and calculate Matlab-compatible output (bug #63411)
* mean.m: Accept large DIM inputs by removing any dimensions larger than the
dimensions of the input array. Use vectorized operations, rather than for
loop, for this input validation. Pre-declare output array before for loop
for performance. Use ipermute() after calculations to return
correctly-dimensioned result (checked with Matlab). Change BIST tests results
to match correct behavior.
