Add templates for Web Extensions page types

[pepelsbey]

Description

It creates templates for six Web Extension page types:

1. webextension-api-function
2. webextension-api
3. webextension-api-event
4. webextension-api-property
5. webextension-api-type
6. webextension-manifest-key

Templates follow a similar structure but have variations depending on the page type needs.

Motivation

Harmonize Web Extensions docs within the section and with the rest of the MDN reference pages.
