Update to esp-hal 0.18.0

[AnthonyGrondin]

• I've updated esp-hal to the latest current release.
• I've locked the nightly version to nightly-2024-06-12 until the fix in macro expansion broken on latest nightly (2024-06-13) embassy-rs/embassy#3078 gets released
• I've reduced heap_size in config to be able to build without overflowing segments.

⚠️ Breaking Change ⚠️

• The rsa field of Session::new() now take the peripheral directly, instead of an instance of the driver, so that we can instantiate the driver ourselves, in blocking mode. This now also allow creating a session in a trait impl that immutably borrow &self without triggering the borrow checker, by declaring a field with RefCell<Option<esp_hal::peripherals::RSA>>, and calling Session::new() with the following for the rsa field:

if let Ok(ref mut rsa) = self.rsa.try_borrow_mut() {
    rsa.as_mut()
} else {
    None
},
