Markus Böck 10a80c4413 [mlir] Implement replacement of SymbolRefAttrs in Dialect attributes using SubElementAttr interface
This patch extends the SubElementAttr interface to allow replacing a contained sub attribute. The attribute that should be replaced is identified by an index which denotes the n-th element returned by the accompanying walkImmediateSubElements method.

Using this addition the patch implements replacing SymbolRefAttrs contained within any dialect attributes.
