Add repr(align(2)) to RcInner and ArcInner

`Rc` currently assumes that `RcInner` has at least 2-byte alignment, but on AVR, `usize` has 1-byte alignment (this is because the AVR has 1-byte register sizes, so having 2-byte alignment is generally useless), breaking this assumption.

9f32ccf35f/library/alloc/src/rc.rs (L3005-L3008)

This PR adds `repr(align(2))` to force `RcInner` to always have at least 2-byte alignment.

Note that `ArcInner` doesn't need `repr(align(2))` because atomic types have the alignment same as its size. This PR adds a comment about this.
