Deprecate duplicative profile key constants

[evan-masseau]

Description

Mark these keys deprecated in advance of next major release in which we can change them to internal. They're inconsistent with iOS and duplicative of explicit setter methods anyway.

Check List

• Are you changing anything with the public API? - YES, deprecating public constants
• Are your changes backwards compatible with previous SDK Versions? - YES, deprecating = no change required yet.
• Have you tested this change on real device?
• Have you added unit test coverage for your changes? N/A
• Have you verified that your changes are compatible with all Android versions the SDK currently supports?

Changelog / Code Overview

Deprecate the profile keys that correspond to identifiers, which have their own setter methods.

• TODO add new constructor so identifiers can optionally be set from constructor
