Move pattern selectivity code from selfuncs.c to like_support.c.

While at it, refactor patternsel() a bit so that it can be used from the LIKE/regex planner support functions as well. This makes the planner able to deal equally well with either operator or function syntax for these operations. I'm not excited about that as a feature in itself, but it provides a nice model for extensions to follow if they want such behavior for their operations. This change localizes the use of pattern_fixed_prefix() and make_greater_string() so that they no longer need be exported. (We might get pushback from extensions about that, perhaps, in which case I'd be inclined to re-export them in a new header file like_support.h.) This reduces the bulk of selfuncs.c a fair amount, removing ~1370 lines or about one-sixth of that file; it's still too big, but this is progress.
