#5956892 Allow only non WPCOM accounts to be edited.

Changes proposed in this Pull Request

As discussed here, WordPress.com account data (First Name, Last Name, Display Name) should not be editable from admins in Calypso. They should be editable only from each WordPress.com user respective https://wordpress.com/me – this path will be fixed here D61970-code for Atomic. This is already happening for Simple sites, with this diff we bring parity for Atomic (& Jetpack) sites too.

Testing instructions

Go to https://wordpress.com/people/team/ for each of the following scenarios and try to edit First Name, Last Name, Display Name for the current and another user.

Simple Sites

• The fields shouldn’t appear for any user
• Nothing should have changed, check for regressions

Atomic Sites

• The fields shouldn’t appear for WordPress.com linked users
• The fields should appear for local created users through /wp-admin/user-new.php

Jetpack Sites
