Kernel: Fetch range once for each iteration of find_regions_intersecting
...
pvs-studio flagged this as a potential optimization.

Kernel: Make KString factories return KResultOr + use TRY() everywhere
...
There are a number of places that don't have an error propagation path
right now, so I've added FIXME's about that.

Kernel: Make Memory::Region::map() return KResult

..and use TRY() at the call sites to propagate errors. :^)

Kernel: Make AddressSpace::add_region() return KResultOr<Region*>
...
This allows us to use TRY() in a few places.

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

Kernel: Tidy up Memory::AddressSpace construction
...
- Return KResultOr<T> in places
- Propagate errors
- Use TRY()

Kernel: Always observe the return value of Region::map and remap
...
We have seen cases where the map fails, but we return the region
to the caller, causing them to page fault later on when they touch
the region.
The fix is to always observe the return code of map/remap.

Kernel: Rename ScopedSpinlock => SpinlockLocker
...
This matches MutexLocker, and doesn't sound like it's a lock itself.

Kernel: Make Process::current() return a Process& instead of Process*
...
This has several benefits:
1) We no longer just blindly derefence a null pointer in various places
2) We will get nicer runtime error messages if the current process does
turn out to be null in the call location
3) GCC no longer complains about possible nullptr dereferences when
compiling without KUBSAN

Kernel: Make Memory::Region allocation functions return KResultOr
...
This makes for some nicer handling of errors compared to checking an
OwnPtr for null state.

Kernel: Make Kernel::VMObject allocation functions return KResultOr
...
This makes for nicer handling of errors compared to checking whether a
RefPtr is null. Additionally, this will give way to return different
types of errors in the future.

Kernel: Remove unused Process pointer in Memory::AddressSpace

Nobody was using the back-pointer to the process, so let's lose it.
