update entity mapping logic for profile fields to include contact subtypes

[kurund]

Overview

Currently fields belonging to contact subtypes are not mapped to correct entity hence it results in a fatal error using profile submit API.

Steps to replicate

• Use Contact Summary Layout extension and add a section using profile with fields that belong to contact sub type.
• Inline edit fails

Proposed solution

• We already update fields that belong to contact types to contact. In this PR I have extended the logic to also include contact subtypes.
