NEXT-36283 - Add names and company of addresses to customer admin es search index

[M-arcus]

1. Why is this change necessary?

When searching in customers for a term that only exists in the first_name, last_name, or company of the address of a customer, the ES admin search does not find the customer. But when clicking “Show all results in customer view”, the customer gets displayed.

2. What does this change do, exactly?

It adds first_name, last_name, and company of table customer_address to customer admin ES search index

3. Describe each step to reproduce the issue or behavior.

1. Have customer with a term that only exists in the field first_name, last_name, or company of an address.
2. Search via ES admin search, no results
3. Click on “Show all results in customer view”, customer is shown as result.

4. Please link to the relevant issues (if any).
