Original change's description:

webnn: Enable kokoro_82m_v1_fp16 model on TFLite backend

The squeeze[1] will output {640} shape tensor if batchSize is 1, the
output tensor will matmul tensor {640, 256}, but the a and b operand
of WebNN matmul[2] are at least 2-D, so remove specific size 1
dimensions at 0 axis with squeeze_dims option.
