Add support for Geofield views filter proximity Longitude and Latitude form

Problem/Motivation

I would like to be able to use tokens in the Geofield manual origin coordinates form in views filter. I want it to be prepopulated with the current user's Geofield field values using tokens. The values are Longitude and Latitude numbers.

Steps to reproduce

Add Geofield proximity filter to views and select manual origin. There is no checkbox to enable tokens for the form.
