Description
SparkSQL - st_buffer function
Currently we have st_bufferPoint. It would be nice to support buffering other geometries.

Research direction
Start by locating the existing st_bufferPoint SparkSQL function and its registration or implementation. Compare how it handles point geometries with the geometry types this feature should support, then verify that st_buffer works for non-point geometries and preserves the expected spatial behavior.
