rust: alloc: allow different error types in `KBox::pin_slice`
Previously, `KBox::pin_slice` required the initializer error type to match
the return error type via `E: From<AllocError>`. This prevented using
infallible initializers like `new_mutex!` inside `pin_slice`, because
`Infallible` does not implement `From<AllocError>`.
Introduce a separate type parameter `E2` for the initializer error type
and require `E: From<AllocError>` and `E: From<E2>` instead. This allows
the initializer to return a different error type that can be converted
into the final error type, enabling use of infallible pin initializers
in fallible allocation contexts.
