Implement `ptr::try_cast_aligned` and `NonNull::try_cast_aligned`.

Implement three common methods on raw pointers and `NonNull`s: `try_cast_aligned`.

## About `#[inline]`

Since the result of a call to `align_of` is a power of two known at compile time, the compiler is able to reduce a call to `try_cast_aligned` to only test and sete (or test and jne if followed by `unwrap`), at least on every tier 1 target's arch. This seemed like a good reason to `#[inline]` the function.
