SERVER-109766 introduced single_table_access.cpp and was forced to compile it as part of the infamous `query_exec` library. This was due to its dependency on QueryPlannerParams which is currently also compiled as part of `query_exec`. Attempting to factor out `query_planner_params.cpp` into a standalone library led to a rabbit hole that was deep enough that we had to give up.

This ticket represents the work to factor out `query_planner_params.cpp` and subsequently `single_table_access.cpp` out into their own libraries. The final build graph should have the following dependencies/edges:

• query_exec
  • query_planner_params
  • single_table_access
• query_planner_params
• single_table_access
  • query_planner_params
