Make transpose optimizer able to look past DQ node for const initializer (#17618) ...

### Description
<!-- Describe your changes. -->
Add ability for transpose optimizer to look past a DQ node if it has a
constant initializer as input. This allows UnsqueezeInput/TransposeInput
to modify the initializer in-place in the same way it would for a
non-QDQ format model.

Shared initializers are also handled, and any additional
Squeeze/Transpose added to the other usages of the initializer should
cancel out when we push the same Transpose though them.

The in-place modification means we don't need to run QDQ fixup and
constant folding after layout transformation. This means we do not need
to enable those optimizers in a minimal build to get an optimal model
post-layout transformation.


### 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. -->
Ensure layout transformation produces optimal model in full and minimal
builds.
