b021fa33b9 Kernel: Correct behavior of Condition Variables to be more similar to real hardware. 
This commit ensures cond var threads act exactly as they do in the real
console. The original implementation uses an RBTree and the behavior of
cond var threads is that at the same priority level they act like a
FIFO.

323a0e17e7 Kernel: Correct Cancel Synchronization. 
This commit corrects the behavior of cancel synchronization when the
thread is running/ready and ensures the next wait is cancelled as it's
suppose to.

63a3b54c1f 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.

eeef564c02 kernel: events: Remove ResetType::Automatic. 
- This does not actually seem to exist in the real kernel - games reset these automatically.

922799f1d5 core: Remove Core::CurrentProcess() 
This only encourages the use of the global system instance (which will
be phased out long-term). Instead, we use the direct system function
call directly to remove the appealing but discouraged short-hand.

ff201725ed kernel/vm_manager: Correct behavior in failure case of UnmapPhysicalMemory() 
If an unmapping operation fails, we shouldn't be decrementing the amount
of memory mapped and returning that the operation was successful. We
should actually be returning the error code in this case.

aed2815ba6 kernel/vm_manager: Reserve memory ahead of time for slow path in MergeAdjacentVMA 
Avoids potentially expensive (depending on the size of the memory block)
allocations by reserving the necessary memory before performing both
insertions. This avoids scenarios where the second insert may cause a
reallocation to occur.
