f4a9a0d561 Kernel: Make VirtualRangeAllocator return KResultOr<VirtualRange> 
This achieves two things:
- The allocator can report more specific errors
- Callers can (and now do) use TRY() :^)

52cbbe1dc5 Kernel: Actually share committed CoW pages 
Due to a double-move mistake, we were always clearing the shared
committed CoW pages in the parent when forking.

This allows us to use TRY() more.

3a9f00c59b Everywhere: Use OOM-safe ByteBuffer APIs where possible 
If we can easily communicate failure, let's avoid asserting and report
failure instead.

bb58a4d943 Kernel: Make all Spinlocks use u8 for storage, remove template 
The default template argument is only used in one place, and it
looks like it was probably just an oversight. The rest of the Kernel
code all uses u8 as the type. So lets make that the default and remove
the unused template argument, as there doesn't seem to be a reason to
allow the size to be customizable.

472454cded Kernel: Switch static_asserts of a type size to AK::AssertSize 
This will provide better debug ability when the size comparison fails.

a9204510a4 Kernel: Make file description lookup return KResultOr 
Instead of checking it at every call site (to generate EBADF), we make
file_description(fd) return a KResultOr<NonnullRefPtr<FileDescription>>.

This allows us to wrap all the calls in TRY(). :^)

The only place that got a little bit messier from this is sys$mount(),
and there's a whole bunch of things there in need of cleanup.

c1e18befe8 Kernel: Reorder sys$pipe() to fail more nicely 
Try to do both FD allocations up front instead of interleaved between
assigning them to the descriptor table. This prevents us from failing
in the middle of setting up the pipes.
