As both of these are in the same memory segment they have no individual
alignment requirements, this created a bug in
にゃんらぶ～私の恋の見つけ方～ where the data segment would be larger
than the game expected and invalid command line arguments would be read.
armed.
It was discovered during testing of 'Hatsune Miku Project DIVA: Mega Mix'
that if a thread was starting while preemption was being enabled a NULL
pointer dereference could occur in the timer_settime call as
timer_create may not have been called yet.
This is used by games before calling into nvdec in order to clock up the
HW module, it can also be used to request a RAM frequency. Since we
obviously don't emulate the hardware down to this level a basic stub
that provides the correct reponses is enough.
Fixes a crash on first level of Super Mario Odyssey.
We used a custom version of Vulkan-Hpp which split the files a lot prior to avoid any developers needing to manually set IDE settings for IntelliJ to work but this wasn't practical due to how it required modifications to Vulkan-Hpp's generator which would make maintenance extremely difficult. It was determined that we should just add the requirement for changing the IDE settings and use Vulkan-Hpp directly.
An RAII scoped trace was used for SvcWaitSynchronization but it was placed within a condition scope which led to an incorrect lifetime for the traces. Minor changes regarding the CR not affecting functionality were made aside from that.
We decided to restructure Skyline to draw a layer of separation between guest and host GPU. We're reserving the `gpu` namespace and directory for purely host GPU and creating a new `soc` directory and namespace for emulation of parts of the X1 SoC which is currently limited to guest GPU but will be expanded to contain components like the audio DSP down the line.
This fixes audio stuttering which occurred on certain BT audio devices by requesting an exclusive stream from Oboe alongside a low-latency stream.

Add Tracing for SVCs, Services, NVDRV, and Synchronization Primitives. In addition, fix `TRACE_EVENT_END("guest")` being emitted when a signal is received while being in the guest rather than host which would cause an exception. This commit also disables warnings for the Perfetto library as we do not control fixing them.
This extend a descriptor table for the SVCs with names for every SVC alongside their function pointer. The names are then used for logging and eventually tracing.
This moves from using std::function with a this pointer binding (which would likely cause a heap allocation) to returning the this pointer in a structure which implements operator() to do the call with it. It also moves to using const char* for strings from std::string_view which was pointless in this scenario due to it's usage being limited to being a C-string for the most part, it also integrates the class name directly into the string which allows us to avoid runtime string concatenation in libfmt and RTTI for finding the class name.
