RUM-7150: Add multiple extension support

[jonathanmos]

What does this PR do?

Support for adding multiple extensions to the session replay configuration.
• If the same extension is added twice we print an error message.
• If several extensions map to the same type we use the first occurrence and print an error message.

Motivation

This will probably be a commonly required use-case.
