promql: Remove unused Point.MarshalJSON method (#9860)

Browse source 
JSON marshaling is only needed for the HTTP API. Since Point is such a
frequently marshaled type, it gets an optimized treatment directly in
web/api/v1/api.go. The MarshalJSON method still provided in the promql
package is therefore unused and its existence is confusing.
