Implement tree explain for FilterExec #15000
Description
Is your feature request related to a problem or challenge?
@irenjj added a new tree explain mode in #14677. Now we need to add support for different types of operators.
set datafusion.explain.format = 'tree';
create table foo(x int, y int) as values (1,2), (3,4);
explain select * from foo where x = 4;

| logical_plan | Filter: foo.x = Int32(4) |

Describe the solution you'd like
Add tree format to the named ExecutionPlan
Roughly speaking the process goes like:
- Add the relevant code to the operator
- Add / update explain_tree.slt test to show the new code in action
You can run the tests like
cargo test --test sqllogictests -- explain_treeYou can update the test like this:
cargo test --test sqllogictests -- explain_tree --completeDescribe alternatives you've considered
