#4299: st_generatepoints declared IMMUTABLE

Comment (by komzpa):
https://postgis.net/docs/ST_GeneratePoints.html says "ST_GeneratePoints
generates pseudo-random points until the requested number are found within
the input area". There is no guarantee that sequence will be the same or
not the same each time. IMMUTABLE only affects caching in Postgres as for
now, and per current documentation it's okay to cache ST_GeneratePoints
output for the same polygon. Will a note about this behavior be
sufficient?
