User Profile Rework

[AliRKat]

Reasons of in this rework:

• Some of the methods were not following the naming conventions we follow in all SDKs (pushValue, pullValue etc.)
• Support for all primitive types and array types in custom user details
• Directly added UserProfile.js because having everything inside Countly.js is not a good idea IMO.
• Old methods were returning messages, which is something we want to move away from, new calls are void

Note: There's also userDataBulk in Countly.js, haven't done anything about that one yet but we can also deprecate that one and apply the same structure to it, wanted to ask about that one first
