Subject: [PATCH] embedded-hal: digital: add #[inline] hints for PinState
 functions

Add inline hints for:

- <PinState as Not>::not
- <PinState as From<bool>>::from
- <bool as From<PinState>>::from

Those hints would allow further optimizations if PinState structure functions is used on embedded-hal projects.
