Generate parameterized paths for columnar scans. (#5172) 
Allow ColumnarScans to push down join quals by generating
parameterized paths. This significantly expands the utility of chunk
group filtering, making a ColumnarScan behave similar to an index when
on the inner of a nested loop join.

Also, evaluate all parameters on beginscan/rescan, which also works
for external parameters.

Fixes #4488.
