core: Switch to unique_ptr for usage of Common::Fiber.
- With using unique_ptr instead of shared_ptr, we have more explicit ownership of the context.
- Fixes a memory leak due to circular reference of the shared pointer.

kernel/scheduler: Mark SchedulerLock constructor as nodiscard
Allows the compiler to warn about cases where the constructor is used
but then immediately discarded, which is a potential cause of
locking/unlocking bugs.

kernel/scheduler: Use std::mutex instead of spin lock
Profiling shows that this is a highly contested mutex, causing dimishing
results compared to a OS lock. std::mutex implementations can spin for a
while before falling back to an OS lock.
This avoids wasting precious CPU cycles in a no-op.

kernel: Resolve sign conversion warnings
Uncovered a bug within Thread's SetCoreAndAffinityMask() where an
unsigned variable (ideal_core) was being compared against "< 0", which
would always be a false condition.
We can also get rid of an unused function (GetNextProcessorId) which contained a sign
mismatch warning.
