XNNPACK: Support 1D input for Conv and ConvTranspose (#20349)
### Description
<!-- Describe your changes. -->
Support 1D input to XNNPACK Conv and ConvTranspose by using faking
height of 1 to convert to 2D input.
### Motivation and Context
<!-- - Why is this change required? What problem does it solve?
- If it fixes an open issue, please link to the issue here. -->
Enable speech model with 1D input to use XNNPACK. There is no CPU EP
quantized ConvTranspose, so this fills that gap.
