  -----------
  [mlir][linalg] Allow promotion to use the original subview size (#144334)

linalg promotion attempts to compute a constant upper bound for the
allocated buffer size. Only when failed to compute an upperbound it
fallbacks to the original subview size, which may be dynamic.

Adding a promotion option to use the original subview size by default,
thus minimizing the allocation size.
Fixes #144268.
