More re-exports in the chip specific HALs needed

[bjoernQ]

We need to re-export more of esp-hal-common since that shouldn't be used directly

Background:
When implementing https://github.com/bjoernQ/ps2keyboard-esp32c3 I discovered I need to import a few things that are actually in esp-hal-common and are not re-exported:

use esp_hal_common::{Event, OpenDrain, Output, Pin};

Removed the "good first issue" label since I think it's because of module shadowing: https://rust-lang.github.io/rfcs/0116-no-module-shadowing.html

So basically, we need to export those items in different namespaces - question is how to name them?
