Add configuration option for sliding sync when hosting /.well-known/matrix/client (#3189)

Browse source 
Adds the `org.matrix.msc3575.proxy` field (used for configuring sliding
sync) to /.well-known/matrix/client when Dendrite is serving that
endpoint and `well_known_sliding_sync_proxy` has been configured.

ie. Config values of:
``` yaml
global:
    well_known_client_name: https://example.com
    well_known_sliding_sync_proxy: https://syncv3.example.com
```
results in a /.well-known/matrix/client of:
``` json
{
    "m.homeserver": {
        "base_url": "https://example.com"
    },
    "org.matrix.msc3575.proxy": {
        "url": "https://syncv3.example.com"
    }
}
```

If `well_known_sliding_sync_proxy` is not provided, the json provided by
/.well-known/matrix/client does not include the proxy field.
ie.
``` json
{
    "m.homeserver": {
        "base_url": "https://example.com"
    }
}
```
