  [mlir][acc] Add LegalizeDataValues support for DeclareEnterOp (#138008)

The patch extends the existing LegalizeDataValues to support
DeclareEnter and DeclareExit pair.
Since unlike other ops, DeclareEnter and DeclareExit don't have a region
defined, we use dominance/post dominance information to ensure only the
uses within the region dominated by DeclareEnter and post dominated by
DeclareExit are updated with data on device.
