Remove some useless oidc variables and /_synapse/oidc route handling 

After some checking, it seems like there's `/_synapse/client/oidc`,
but no such thing as `/_synapse/oidc`.

I'm not sure why we've been reverse-proxying these paths for so long
(even in as far back as the `matrix-nginx-proxy` days), but it's time we
put a stop to it.

The OIDC docs have been simplified. There's no need to ask people to
expose the useless `/_synapse/oidc` endpoint. OIDC requires
`/_synapse/client/oidc` and `/_synapse/client` is exposed by default
already.

```
**NOTE**: if you inject the OIDC configuration using `matrix_synapse_configuration_extension_yaml` (instead of `matrix_synapse_oidc_enabled: true` + `matrix_synapse_oidc_providers` as explained above), then the OIDC routes (`/_synapse/oidc`) will not be publicly exposed automatically. In such a case, you'd need to expose them manually by toggling: `matrix_synapse_container_labels_public_client_synapse_oidc_api_enabled: true`.
