  Log Message:
  -----------
  [MLIR] [Vector] Added canonicalizer for folding from_elements + transpose (#161841)

## Description
Adds a new canonicalizer that folds
`vector.from_elements(vector.transpose))` => `vector.from_elements`.
This canonicalization reorders the input elements for
`vector.from_elements`, adjusts the output shape to match the effect of
the transpose op and eliminating its need.

## Testing
Added a 2D vector lit test that verifies the working of the rewrite.
