[core] Remove any from React.ReactElement types

[DiegoAndai]

Context

In the upcoming React 19 @types/ packages, the props of ReactElement now default to unknown instead of any.

We have many occurrences that rely on ReactElement props being any (the previous default). To migrate to React 19, the any type was specified explicitly in #42346, so we can keep the previous default behavior.

This issue

We should gradually remove any and rely on the new default, unknown. This is what this issue is tracking.

Hey @fedirjh! Sure 😊, go ahead. There are a lot of occurrences, so please divide the work into smaller PRs if possible.

Let me know if you need any help. Thanks in advance.

@sai6855 I think the only ones left to migrate are the ones missing in https://github.com/sai6855/material-ui/blob/master/packages-internal/test-utils/src/describeConformance.tsx

Oops i missed addressing these, opened PR to remove those #44639

Thanks @sai6855! Nice work.

With this, we've removed all any from React.ReactElement where possible. There are still a couple of edge cases where it was required, but I consider this as completed.
