79fa9765ca Kernel: Replace KResult and KResultOr<T> with Error and ErrorOr<T> 
We now use AK::Error and AK::ErrorOr<T> in both kernel and userspace!
This was a slightly tedious refactoring that took a long time, so it's
not unlikely that some bugs crept in.

Nevertheless, it does pass basic functionality testing, and it's just
real nice to finally see the same pattern in all contexts. :^)

7ee10c6926 AK: Add some more ways to construct Error and ErrorOr<T> 
This is preparation for using Error in the kernel instead of KResult.

e841f3c283 AK: Add a variant of adopt_nonnull_own_or_enomem() for userspace 
This variant returns ErrorOr<NonnullOwnPtr<T>> instead of KResultOr.
Eventually the KResultOr variant should go away once the kernel adopts
Error and ErrorOr<T>.

880964755b AK: Don't define AK_HAS_CONDITIONALLY_TRIVIAL when parsed by CLion IDE 
This feature confuses CLion's parser, so let's turn it off if we see the
__CLION_IDE_ macro as well.

202950bb01 AK: Make Error and ErrorOr<T> work in Lagom as well :^) 
ErrnoCode is not a thing outside __serenity__, so let's not make
assumptions about it existing.

09cba7c780 LibGfx: Use ErrorOr<T> for Bitmap infrastructure used by ShareableBitmap 
This also allows us to get rid of the ShareableBitmap(Bitmap)
constructor which was easy to misuse. Everyone now uses Bitmap's
to_shareable_bitmap() helper instead.

2116620db8 AK: Add ErrorOr<T>::release_value_but_fixme_should_propagate_errors() 
This is an alternative to ErrorOr<T>::release_value() that can be used
when converting code to signal that we're releasing the value without
error propagation as a way to move forward now.

This makes these cases much easier to find later on, once more paths for
error propagation are available.

c6b4e7a2f6 LibIPC: Add ClientConnection::shutdown_with_error() 
Before this, we only had ClientConnection::did_misbehave() to report an
error and shut the connection down. But it's not fair to say that *all*
errors are the client misbehaving! A typical non-misbehavior is resource
allocation failure on the server side.

56992f90b7 AK: Add adopt_nonnull_ref_or_enomem() for userspace

as well. This return an ErrorOr<NonnullRefPt<T>>. :^)

c4edb9f6c2 AK: Add Error and ErrorOr<T> 
The goal with these is to eventually replace AK::Result, KResult and
KResultOr<T> with something that works (and makes sense) in both kernel
and userspace.

This first cut of Error can be made from an errno code, or from a string
literal (StringView)
