[Feature] Support for FE division of execution groups

[stdpain]

Why I'm doing:

Divide the execution group when building the planfragment. For colocate join/agg put into execution group. Nodes in the same execution group can create more operators.

sesssion variables:

enable_group_execution: whether to enable group execution
group_execution_group_scale: Controls the number of groups to dismantle. The number of groups to split is min(dop x scale, group_nums, max_group_nums)
group_execution_max_groups: max group nums

What I'm doing:
