Replaced custom memory addr type with memory_address

[jounathaen]

This removes the align_down_to_base_page etc. functions, as well as some operators (e.g., rem). But these can be easily replaced with, e.g., use align_address::Align; myaddr.align_down(BASE_PAGE_SIZEl);

-> requires a version bump

To fix clippy, this is now also non-nightly at the cost of requiring Rust 1.82

I don't think we'd want this crate to depend on memory-addresses but the other way around to make this crate self-governing regarding the guarantees and arch-specific methods on these types.

Let's talk about it. :)
