Make it possible to override JSON schema generation for tools

[dmontagu]

In some cases you might want to have a bit more control over the generated JSON schema; see discussion in this thread https://pydanticlogfire.slack.com/archives/C083V7PMHHA/p1741204403143859.

I'll note there's a couple TODO comments in the PR currently that should be considered before merging/not.
