Try to reconcile all given UnrealizedConversionCastOps and store the left-over ops in remainingCastOps (if provided).
See documentation in DialectConversion.h for more details. The isCastOpOfInterestFn is used to filter the cast ops to proceed: the algorithm may visit an operand (or user) which is a cast op, but will not try to reconcile it if not in the filtered set.

Marker attribute for pure type conversions.
I.e., mappings whose only purpose is to resolve a type mismatch. (In contrast, mappings that point to the replacement values of a "replaceOp" call, etc., are not pure type conversions.)
