Fucun Chu 77d6acd032 IMPALA-10581: Implement ds_theta_intersect_f() function ...

This function receives two strings that are serialized Apache
DataSketches Theta sketches. Computes the intersection of two sketches
of same or different column and returns the resulting sketch of
intersection.

Example:
select ds_theta_estimate(ds_theta_intersect_f(sketch1, sketch2))
from sketch_tbl;
+-----------------------------------------------------------+
| ds_theta_estimate(ds_theta_intersect_f(sketch1, sketch2)) |
+-----------------------------------------------------------+
| 5                                                         |
