  [MLIR][XeGPU] Use context-aware type converter in WgToSgDistribute and Blocking pass (#194685)

This PR replaces the TypeConverter in xegpu-wg-to-sg-distribute and
xegpu-blocking with a context-aware converter that picks each value's
converted type from the layout attached to its defining op/use, removing
the need for the UnrealizedConversionCastOpPattern workaround for scf
ops.
