feat(datautils): Map deep copy + For Each

[Cobalt0s]

Description

• Extended ForEach to support error exit via ForEachWithErr.
• ToAnySlice converts []myType to []any. Otherwise need to create slice and populate the usual way while it is simple conversion, in golang there is not OOB solution.
• Map deep copy will be used for creating payload from each Record. To avoid modifying the same data structure, I am using deep copy.

Have we tested these utils in someway to verify them, especially edge cases like empty and error scenarios?
