[raster] Add geometry filtered variations for various statistics functions

Description

It would be nice to use a geometry to filter a raster and then compute the statistics for the filtered raster.

These functions would probably be built upon ST_Intersection and kept in plpgsql unless it is found that performance is lacking.

I would say that now that we have a C version of ST_Clip, we don't really need this option anymore. Up to you to keep or close it. Would be a lot of work in many stats functions.

I'll keep it for now. Once aggregate versions of the stats functions are done, this is worth revisiting...
