1. Fix Wii Speak SAMPLER_MUTE register:
The register should be 12 (i.e. 0x0c) instead of 0xc0.
2. Fix Wii Speak buffer memcpy size parameter:
It seems to fix random echoes and reduce noises when nobody is speaking.
3. Change the isochronous transfer timing:
It is based on empirical testing.
Based on @noahpistilli (Sketch) PR:

Fixed the Windows support and the heisenbug caused by uninitialized
members.
Config system integration finalized.
I've been playing Rock Band 3 recently and have experienced a bug where
sometimes if you disconnect and reconnect a USB microphone, the game
won't pick up on it connecting, not even it you disconnect and reconnect
it again. An investigation into what's going on inside Dolphin shows
that when the game triggers a call to OH0::DeviceOpen after the device
has been reinserted, Dolphin doesn't open the device because it's
already present in m_opened_devices.
Removing the device from m_opened_devices after calling OH0::TriggerHook
in OH0::OnDeviceChange resolves this specific issue in my testing. Doing
this matches us removing the device from m_opened_devices after calling
OH0::TriggerHook in OH0::DeviceClose, but I haven't looked at exactly
what real IOS does.
I have been able to reproduce a much rarer issue that has the same
symptoms on the surface but where OH0::DeviceOpen gets past its
m_opened_devices check. I'm currently not sure what the cause of this
remaining issue is.
Some games open two USB interfaces, e.g. /dev/usb/oh0 and /dev/usb/hid.
This was causing us to run two scanning threads at once, using up more
CPU time for scanning than we need to.
Instead of having USBScanner create "hooks" as it scans for devices,
let's have USBScanner present a list of devices to USBHost and have
USBHost diff the new device list with its old device list to create the
hook calls instead. This gets rid of some complex edge cases that the
next commit otherwise would have to deal with, in particular regarding
toggling determinism and adding new USBHosts to a USBScanner.
Note: After adding the missing locking of m_devices_mutex, I had to move
the locking of m_hooks_mutex to avoid a random deadlock between the CPU
thread and USB scanning thread. (Either that or I would have to lock
m_devices_mutex before m_hooks_mutex.)
This gets rid of the ugly direct access to USBScanner::m_devices that
was introduced by the previous commit.
This also fixes a potential thread safety issue.
USB_HIDv4::TriggerDeviceChangeReply loops through m_devices and calls
GetDeviceEntry for each device. If USB_HIDv4::TriggerDeviceChangeReply
is called after a new device is added to m_devices but before hooks are
dispatched, GetDeviceEntry crashes, because the hook that's supposed to
update m_device_ids hasn't run yet. With this commit, this issue can no
longer happen, because USBHost::m_devices_mutex doesn't get unlocked in
between updating m_devices and dispatching the hooks.
This lets you use PS3 Rock Band controllers with Wii Rock Band and
Guitar Hero games.
A normal user will probably never have any reason to disable this
behavior, but I figured maybe there's some person out there who would
like to disable it. (For instance, I know there's a mod for RB3 that's
trying to implement the same kind of cross-console controller
compatibility, and that can only be tested if the behavior I'm adding is
disabled.) So the behavior is controlled by an INI-only setting.
In PPCTables.cpp, the code is currently unused so I was unable to test it.
In CustomPipeline.cpp, a pointer to member function cannot be used due to 16.4.5.2.1 of the C++ Standard regarding "addressable functions". https://eel.is/c++draft/namespace.std#6
In Fs.cpp and DirectoryBlob.cpp, these examples used projections in a previous iteration of this commit, but no longer do. Still, they remain in this commit because the PR they would actually belong to is already merged.
In LabelMap.cpp, the code is currently unused so I was unable to test it.
In WiiUtils.cpp, the magic value `1u` was replaced by the constant value `DiscIO::PARTITION_UPDATE`.
In WiimoteReal.cpp, JitRegCache.cpp, lambda predicates were replaced by pointers to member functions because ranges algorithms are able invoke those.
In ConvertDialog.cpp, the `std::mem_fn` helper was removed because ranges algorithms are able to handle pointers to member functions as predicates.
In DITSpecification.cpp, MaterialAsset.cpp, and ShaderAsset.cpp, lambda predicates were replaced by pointers to member functions because ranges algorithms are able invoke those.
In NetPlayClient.cpp, the non-trivial `NetPlay::Player` elements were being passed by value in `NetPlayClient::DoAllPlayersHaveGame()`. This has been fixed.
In WIABlob.cpp, the second example's predicate was returning the `std::optional` by value instead of implicitly converting it to a bool. This has been fixed.
