42f5fd0ab3 core/core_timing_util: Use std::chrono types for specifying time units
Makes the interface more type-safe and consistent in terms of return
values.

c5d41fd812 core/core_timing: Make callback parameters consistent
In some cases, our callbacks were using s64 as a parameter, and in other
cases, they were using an int, which is inconsistent.

To make all callbacks consistent, we can just use an s64 as the type for
late cycles, given it gets rid of the need to cast internally.

While we're at it, also resolve some signed/unsigned conversions that
were occurring related to the callback registration.

0e1b5acc6a audio_core/audio_renderer: Name previously unknown parameters of AudioRendererParameter
Provides names for previously unknown entries (aside from the two u8
that appear to be padding bytes, and a single word that also appears
to be reserved or padding).

This will be useful in subsequent changes when unstubbing behavior related
to the audio renderer services.

bd983414f6 core_timing: Convert core timing into a class
Gets rid of the largest set of mutable global state within the core.
This also paves a way for eliminating usages of GetInstance() on the
System class as a follow-up.

Note that no behavioral changes have been made, and this simply extracts
the functionality into a class. This also has the benefit of making
dependencies on the core timing functionality explicit within the
relevant interfaces.

6beb823f15 audio_core: Make g_sink_details internally linked
We can hide the direct array from external view and instead provide
functions to retrieve the necessary info. This has the benefit of
completely hiding the makeup of the SinkDetails structure from the rest
of the code.

Given that this makes the array hidden, we can also make the array
constexpr by altering the members slightly. This gets rid of several
static constructor calls related to std::vector and std::function.

Now we don't have heap allocations here that need to occur before the
program can even enter main(). It also has the benefit of saving a
little bit of heap space, but this doesn't matter too much, since the
savings in that regard are pretty tiny.

2534af040e Fixed missing return
Softlock explanation:
after effects are initialized in smo, nothing actually changes the state. It expects the state to always be initialized. With the previous testing, updating the states much like how we handle the memory pools continue to have the softlock(which is why I said it probably wasn't effects) after further examination it seems like effects need to be initialized but the state remains unchanged until further notice. For now, assertions are added for the aux buffers to see if they update, unable to check as I haven't gotten smo to actually update them yet.

Complete the device switching implementation by allowing the output
device to be loaded, changed and saved through the configurations menu.

Worked with the Sink abstraction and tuned the "Device Selection"
configuration so that the Device List is automatically populated when
the Sink is changed.
This hopefully addresses the concerns and recommendations mentioned in
the comments of the PR.

004991d79e DSP: Implement Pipe 2
Pipe 2 is a DSP pipe that is used to initialize both the DSP hardware (the
application signals to the DSP to initialize) and the application (the DSP
provides the memory location of structures in the shared memory region).

8b00954ec7 AudioCore: Skeleton Implementation
This commit:
* Adds a new subproject, audio_core.
* Defines structures that exist in DSP shared memory.
* Hooks up various other parts of the emulator into audio core.

This sets the foundation for a later HLE DSP implementation.
