video_core: gpu: WaitFence: Do not block threads during shutdown.

- This is breaking our build pipelines with Zydis (dynarmic dependency).

applets/swkbd: Only read the text check message on Failure/Confirm

ldn: Add and stub lp2p:sys lp2p:app INetworkServiceMonitor INetworkService

Mario Kart Live: Home Circuit needs lp2p:sys lp2p:app INetworkServiceMonitor INetworkService to be able to progress.

Note: The game still fails to boot from unimplemented LDN and BSD services.

externals: Update dynarmic.

kernel: Add missing override specifiers

k_thread: Move dereference after null check in Initialize()

- Fixes a hang on shutdown when NVFlinger thread is waiting on a syncpoint that will never occur.
- Commonly observed when stopping emulation in Super Mario Odyssey.

hle: kernel: KSlabHeap: Allow host or guest allocations.

Fix two GCC 11 warnings: Unneeded copies.

Over the course of the kernel refactoring a tiny bit of missing
overrides slipped through review, so we can add these.

While we're at it, we can remove redundant virtual keywords where
applicable as well.

std::move created an unneeded copy.
iterating without reference also created copies.

The new version supports fastmem on a64.

Prevents a -Wnonnull warning on GCC.

core/arm_interface: Call SVC after end of dynarmic block.

- 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.

common/fs/file: Default initialize IOFile members

Relocates them to the same place the move equivalents are at for
consistent viewing.

IOFile is a final class, so there's no need for a virtual destructor.

Prevents a potential uninitialized read vector in the move constructor.

Avoids redundant string copies

Applications may leave this region of memory uninitialized when the text check result is not either Failure or Confirm.
Attempting to read uninitialized memory may cause an exception within the UTF16 to UTF8 string converter.
Fix this by only reading the text check message on Failure or Confirm.

video_core: rasterizer_cache: Use u16 for cached page count.

- Greatly reduces the risk of overflow, at the cost of doubling the size of this array.

So we can modify all of dynarmic states within SVC without ExceptionalExit.

Especially as the ExceptionalExit hack is dropped on upstream dynarmic.

cmake: Fix usage of CMAKE_DEPENDENT_OPTION

yuzu qt: Add an Apply button to configuration dialogs

CMAKE_DEPENDENT_OPTION takes a value argument, but as a macro function
it will read a variable name as the name and not the value. For
YUZU_USE_BUNDLED_QT, ensure that we are reading the value of MSVC. For
YUZU_ALLOW_SYSTEM_SDL2, CMAKE_DEPENDENT_OPTION is redundant here anyway
as we don't use that path on any toolchain by default.

cmake: Download Qt binaries on Linux if needed

core/arm: Drop ChangeProcessorID.

If the local version of Qt is older than the minimum version required by
yuzu, download a pre-built binary package from yuzu-emu/ext-linux-bin
and build yuzu with it, instead.

This also requires linking yuzu to the correct libraries after building
it, and copying over the required binaries when building yuzu.

This sets the Qt requirement to 5.12, which is intentionally behind the
versions used by our toolchains since they are not all updated yet to
5.15.

This code was used to switch the CPU ID on thread switches.
However since "hle: kernel: multicore: Replace n-JITs impl. with 4 JITs.", the CPU ID is not a constant.
This has been dead code since this rewrite, and dropped in dynarmic as well. So there is no need to keep it.
