### What problem does this PR solve?

This is a follow-up of #7088 , adding a knowledge base type input to the
`Begin` component, and a knowledge base selector to the agent flow debug
input panel:

then you can select one or more knowledge bases when testing the agent:

Note: the lines changed in `agent/component/retrieval.py` after line 94
are modified by `ruff format` from the `pre-commit` hooks, no functional
change.

Fix #6600

Hello, I have the same business requirement as #6600. My use case is: 

We have many departments (> 20 now and increasing), and each department
has its own knowledge base. Because the agent workflow is the same, so I
want to change the knowledge base on the fly, instead of creating agents
for every department.

It now looks like this:

Knowledge bases can be selected from the dropdown, and passed through
the variables in the table. All selected knowledge bases are used for
retrieval.
