assert: add position and pass msg to underlying func in InDeltaMapValues, InDeltaMapValues, and InEpsilonSlice

[hendrywiranto]

Summary

Add position and pass msg to underlying func in InDeltaSlice, InDeltaMapValues, and InEpsilonSlice

Changes

• Add position information into the msgAndArgs slice in those 3 funcs
  • at index: for slice index
  • at key: for map key

Motivation

When using those 3 functions, users don't know which key/index of the map/slice that produces the error because currently it's not added into the msgAndArgs slice.
