Was getting an unhandled `invalid_argument` [exception](https://en.cppreference.com/w/cpp/thread/thread/join) during
shutdown on my linux machine. This removes the need for a `StopBackendThread` function entirely since `jthread`
[automatically handles both checking if the thread is joinable and stopping the token before attempting to join](https://en.cppreference.com/w/cpp/thread/jthread/~jthread) in the case that `StartBackendThread` was never called.

externals: Dynarmic: Update to latest rev.

- Fixes inaccurate size reporting in SpaceRemaining, which caused crashes in yuzu with SSBU.

Add extended memory layout (6GB) support and improve KResourceLimit management

vulkan_device: Blacklist RADV on RDNA2 from VK_EXT_vertex_input_dynamic_state

maxwell_to_(gl/vk): Add 11_11_10 float vertex format

RDNA2 devices running under the RADV driver were crashing when VK_EXT_vertex_input_dynamic_state was enabled.

Blacklisting these devices until a proper fix is established.

- Used by パワプロクンポケットR

vk_blit_screen: Add missing framebuffer format

yuzu: Disconnect amiibos on drag and drop

input_common: Remove battery duplicated struct and update every button press

service: am: Update enum names to match documentation

vulkan_device: fix missing format in ANV

hle: kernel: KSystemControl: Use 6GB memory layout when "use_extended_memory_layout" setting is enabled.

- This uses a larger 6GB DRAM memory layout, which is useful for some mods that require more memory.

- That way, we can consolidate the memory layout to one place.

- This will be used to enable emulation of a larger memory arrangement.

- With prior changes, we now report the correct amount of physical memory available to the emulated process.

- This allows us to have a resource limit per process, rather than use the global system resource limit.

- This is necessary to ensure resource limits are freed from the right process.

core: hle: kernel: KResourceLimit: Add a helper function for creating a KResourceLimit for a process.

core: hle: kernel: KPageTable: Improve Un/MapPhysicalMemory.

core: hle: kernel: KPageTable: Fix UnmapPages.

Currently Mesa's ANV driver does not support
VK_FORMAT_B5G6R5_UNORM_PACK16, implement an alternative for it.

nfp: Improve amiibo support

- Fixes a logic bug in KPageTable::UnmapPages.

- Improves the implementations of MapPhysicalMemory and UnmapPhysicalMemory to more closely reflect latest HOS.

yuzu: config: Fix mapping issues with the enter key

common: Add NullVisitor default constructor

Addresses https://github.com/yuzu-emu/yuzu/issues/7881 to fix linux
builds.

`YUZU_NON_COPYABLE` deletes the `T(const T&)` constructor which will
cause the implicitly defined default ctor/dtor to no-longer generate.

kernel: svc: Add OutputDebugString32, CreateCodeMemory32, ControlCodeMemory32

service/mnpp: Stub mnpp_app

file_sys: Dump patched exefs rather than base

audio_core: Update current process revision

common: fs_util: Add buffer to string view utility functions
