0586924bbd LibELF+Lagom: Work towards getting LibELF in Lagom 
Mostly -Wformat fixes, some of which pointed out real (if benign) bugs.

9f685ac30a AK: Add static_ptr_cast support for the Userspace<T> pointer type 
When using Userspace<T> there are certain syscalls where being able
to cast between types is needed. You should be able to easily cast
away the Userspace<T> wrapper, but it's perfectly safe to be able to
cast the internal type that is being wrapped.

0d6597df2b AK: Remove Stream::operator bool() 
This was only used in one place, and that caused a bug, so I'm removing
this for now since there are no more uses.

b3d1a05261 Refactor: Expose const_cast by removing ByteBuffer::warp(const void*, size_t) 
This function did a const_cast internally which made the call side look
"safe". This method is removed completely and call sites are replaced
with ByteBuffer::wrap(const_cast<void*>(data), size) which makes the
behaviour obvious.

fa625a2690 AK: Decorate AK::OwnPtr::leak_ptr() with [[nodiscard]] 
We should always leak to an observed variable, otherwise
it's an actual leak. This is similar to AK::RefPtr::leak_ref()
which is also marked as [[nodiscard]].

efb0805d8e AK: Add SinglyLinkedListWithCount<T>, a singulary linked list with count 
There are use cases where a linked list is useful but it's also worth
the overhead to maintain a count so you can quickly answer queries of
the size of the list.

9bcf0b70cb AK: Hack Userspace<T> to not break Qt Creator syntax highlighting 
This is a very cheesy patch and I don't like it, but as Qt Creator does
not grok C++20 concepts yet, this makes it possible to still use syntax
highlighting.

We'll remove this hack the moment it stops being a problem. Note that
it doesn't actually affect the build since we use GCC, not Clang.

5bf994d2d9 AK: Use C++20 concepts to only allow Userspace wrappers of pointers 
It was a bit odd that you could create a Userspace<int> and that
Userspace<int>::ptr() returned an int instead of an int*.

Let's use C++20 concepts to only allow creating Userspace objects with
pointer types. :^)

628b3badfb Kernel+AK: Add and use Userspace<T>::unsafe_userspace_ptr() 
Since we already have the type information in the Userspace template,
it was a bit silly to cast manually everywhere. Just add a sufficiently
scary-sounding getter for a typed pointer.

Thanks @alimpfard for pointing out that I was being silly with tossing
out the type.

In the future we may want to make this API non-public as well.

e39a410546 AK: Add Userspace<T>, a wrapper for userspace pointers 
This will be used in the kernel to wrap pointers into userspace memory
without convenient direct access. The idea is to use the compiler to
enforce that we don't dereference userspace pointers.
