49adebf0fc strace: Use new PT_PEEKBUF function 
This necessarily introduces some usages (and benefits!) of the new
ErrorOr<> pattern. To keep commits atomic, I do not yet rewrite the
entire program to use ErrorOr<> correctly.

0f8483f09c Kernel: Implement new ptrace function PT_PEEKBUF 
This enables the tracer to copy large amounts of data in a much saner
way.

3e223185b3 Kernel+strace: Remove unnecessary indirection for PEEK 
Also, remove incomplete, superfluous check.
Incomplete, because only the byte at the provided address was checked;
this misses the last bytes of the "jerk page".
Superfluous, because it is already correctly checked by peek_user_data
(which calls copy_from_user).

The caller/tracer should not typically attempt to read non-userspace
addresses, we don't need to "hot-path" it either.

6f37510a71 AK: Implement missing const getters in AK::Error, fix typo 
Note that the return type for the non-const method error() changed. This
is most likely an accident, hidden by the fact that ErrorType typically
is Error.

dbd60f9ff4 AK: Implement Formatter for ErrorOr<> 
As the Formatter for Error already exists, this apparently was just
accidentally omitted.

c6a97ea843 Kernel: Mark kernel smart-pointer classes as [[nodiscard]]

5013a6480d AK: Mark smart pointer classes as [[nodiscard]] 
This makes it an error to not do something with a returned smart
pointer, which should help prevent mistakes. In cases where you do need
to ignore the value, casting to void will placate the compiler.

I did have to add comments to disable clang-format on a couple of lines,
where it wanted to format the code like this:

```c++
private : NonnullRefPtr() = delete;
```

f3d8f80e9c IPCCompiler: Cast return value of synchronous void IPC calls to void 
The synchronous call returns a NonnullOwnPtr that we don't use, so we
have to cast to prevent a compiler warning once smart pointers become
[[nodiscard]].

d2024f04bd Userland: Cast unused BackgroundAction::construct() results to void 
User code does not need to keep this alive, so casting to void is safe.
But maybe a bit weird.

92f8514a85 Services: Cast unused IPC::new_client_connection() results to void 
These ones all manage their storage internally, whereas the WebContent
and ImageDecoder ones require the caller to manage their lifetime. This
distinction is not obvious to the user without looking through the code,
so an API that makes this clearer would be nice.
