feat(components): added location component

[laurentlp]

This PR adds the location component and enables its support on the webchat.

It requires a Google Maps API Key to be set in the webchat config: https://developers.google.com/maps/documentation/javascript/get-api-key

api.rest

### Send Location
POST {{baseUrl}}/api/v1/messages
Authorization: Bearer {{authToken}}
x-bp-messaging-client-id: {{clientId}}
x-bp-messaging-client-token: {{clientToken}}
Content-Type: application/json

{
  "conversationId": "{{convoId}}",
  "payload": {
    "type": "location",
    "latitude": -25.363,
    "longitude": 130.044,
    "title": "",
    "address": "Uluru (Ayers Rock)"
  }
}

DEV-2299 Webchat: Location content is not supported

[samuelmasse]

Tested and working 👍

Don't forget that the title and address are also parts of the location message. We show them to the user on every channel, so it would make sense to show them in the webchat also. I'm also not a fan of the hardoced Location: prefix for the fallback

With a valid API key
