The gdal/swig/python/samples/ogr_layer_algebra.py should be promoted to an official Python script

Steps:

• move it to gdal/swig/python/scripts
• create a new test script for it in autotest/pyscripts/test_ogr_layer_algebra.py
• write a documentation page in doc/source/programs/ogr_layer_algebra (and link it to the index)

I propose that we create an example section in the Documentation for both the API and CLI. Possible contents are, but not limited to:

• most common use cases
• advanced use of geometries, wildcards, queries, order-by etc.
• unexpected behaviour by the Open Access Hub
• automated workflows

This is a beginner friendly issue. A good starting point would be #140 and then build

Besides, I re-trained the clas
