This is a follow-up of
https://github.com/Significant-Gravitas/AutoGPT/pull/8752
There are several APIs and functions related to graph execution that are
unused now.
There is also confusion about the name of `GraphExecution` that exists
in graph.py & execution.py.
### Changes 🏗️
* Renamed `GraphExecution` in `execution.py` to `GraphExecutionEntry`,
this is only used as a queue entry for execution.
* Removed unused `get_graph_execution` & `list_executions` in
`execution.py`.
* Removed `with_run` option on `get_graph` function in `graph.py`.
* Removed `GraphMetaWithRuns`
* Removed exposed functions only for testing.
* Removed `executions` fields in Graph model.
