Move planner row-estimation tests to new planner_est.sql
Move explain_mask_costs() and the associated planner row-estimation
tests from misc_functions.sql to a new regression test file,
planner_est.sql.
Previously, there wasn't an ideal home for such tests, likely as there
were very few such tests due to width and selectivity estimations being
too dependent on statistics and hardware. That's not always the case, as
we have SupportRequestRows support functions. More such tests are
possibly on the way, so let's create a better home so that we don't have
to create the explain_mask_costs() function in each file we might have
added such tests to.
