8b109f8a69 core: hle: kernel: Allocate dummy threads on host thread storage. 
- Fixes a crash where on subsequent boots, long-lived host threads would have their dummy threads freed.

18baef2ec9 core: hle: kernel: Downgrade dangling objects warning to debug. 
- It is not impossible to leak kernel objects, so this is not really any issue anymore (albeit, still interesting).

29924a999e core: hle: kernel: Remove server session tracking. 
- These are now allocated/managed by emulated memory, so we do not need to track and free them on shutdown.

4b022badf0 core: hle: kernel: Update init_slab_heap, use device memory, and add KThreadLocalPage and KPageBuffer. 
- Refreshes our slab initialization code to latest known behavior.
- Moves all guest kernel slabs into emulated device memory.
- Adds KThreadLocalPage and KPageBuffer, which we will use for accurate TLS management.

fbab3dc017 hle: kernel: Fix service_threads access to be thread safe V2. 
- PR #7699 attempted to fix CreateServiceThread and ReleaseServiceThread to be thread safe, but inadvertently introduced a possible dead-lock.
- With this PR, we use a worker thread to manage the service thread list, allowing it only to be accessed by a single thread, and guaranteeing threads will not destroy themselves.
- Fixes a rare crash in Pokemon Sword/Shield, I've now run this game for ~12 hours non-stop and am quite confident this is a good solution for this issue.

ef9186172f hle: kernel: Fix service_threads access to be thread safe. 
- CreateServiceThread and ReleaseServiceThread can be accessed by different threads, uses a lock to make this thread safe.
- Fixes a rare crash in Pokemon Sword/Shield that can occur when a new service thread is being created while an old one is being destroyed.

722f9c3cb5 common: Replace common_sizes into user-literals 
Removes common_sizes.h in favor of having `_KiB`, `_MiB`, `_GiB`, etc
user-literals within literals.h.

To keep the global namespace clean, users will have to use:

```
using namespace Common::Literals;
```

to access these literals.

639baf88f7 hle: kernel: KSlabHeap: Allow host or guest allocations. 
- Use host allocations for kernel memory, as this is not properly emulated yet.
- Use guest allocations for TLS, as this needs to be backed by DeviceMemory.
