This commit fixes a transpose_conv2d verifier check which compares the output channels size to the bias size. The check didn't make sure output channels were static before performing the comparison. This lead to failures such as:

'tosa.transpose_conv2d' op bias channels expected to be equal to output channels (-9223372036854775808) or 1, got 5

when the output channels size was dynamic.
