Original description

Fix generic plans for FK checks and prepared statements

Fixes #8241

There were two issues with generic plans:

1. We didn't expand hypertables for FK checks for generic plans because we checked for params being passed in, but they were only passed in for custom plans, for generic plans NULL is passed. So FK prep work wasn't done for FK checks with generic plans. Now we also check for external params in the query.

2. Update/Delete on compressed chunks can create partial chunk instead of purely compressed one. This should invalidate any plans relying on this chunk as its status has changed. It is now invalidated similar to

   timescaledb/src/nodes/chunk_dispatch/chunk_insert_state.c

   Line 592 in 71ccb71

   ts_chunk_set_partial(chunk);
