Fixes #420
Description of Changes
Adds the ability to capture and replay workloads that pass SVM or USM pointer kernel arguments that point into the middle of an SVM or USM allocation, in addition to workloads that pass pointers to the base of an SVM or USM allocation. This is done by capturing the offset from the base of an SVM allocation when a pointer is set as a kernel argument. Then, this offset is re-applied during replay.
Testing Done
Tested with several small testers that pass pointers into the middle of an SVM allocaiton. Tested cases where the pointer to the middle of an SVM allocation is an input and where the pointer is an output.
