feat: Add tool_vectordb feature to goose crate

[shawn111]

I'm trying build goose on termux and found it is too slow to build.

In #3914, discuss how to reduce the size of goose.

Change tool_vectordb not as default maybe a quick way to improve.

thanks, we're working on this: #3933 to remove all that. I hope we can get that in this week, can you see if that does the trick for you?

Cool, thanks. Let me close it.
