Do not account for high bit depth twice.

When calculating the stride (for packed formats) and alloc_size, we
should not account for high bit depth twice.

bps accounts for high bit depth (implicitly).

stride_in_bytes also accounts for high bit depth.

So any value calculated by multiplying bps and stride_in_bytes ends up
accounting for high bit depth twice. A solution is to divide bps not by
a fixed 8 bits but by a variable (bit_depth) that is either 8 bits or 16
bits depending on the bit depth.
