The low-pass and biquad filters run in set40 mode where accessing ac#.m
returns the value of ac#.hm clamped to 16 bits.
This fixes the crackling in "Need for Speed: Nitro" (issue 13610).
Also make the lower bound match hardware (-0x8000 instead of -0x7FFF).
I wasn't aware that even with a size of zero, it's still not safe to pass a nullptr to `std::memcpy`. When `CachedInterpreterEmitter::PoisonCallback` is written, UB is happening.
Invert conditions, invert decrement checks, and make conditional branches unconditional. USnapshotMetadata in prior versions of Dolphin is forward-compatible with these changes (tested on x86_64).
Objects which get parented automatically by later processing now pass a nullptr to the constructor to make the intent clearer. Also fixed "true" and "false" not being translatable strings.
This is a minor improvement to add line numbers to the LOG_VULKAN_ERROR
define. Basically error logs for Vulkan will now look like:
```
// This
25:03:347 VideoBackends/Vulkan/VulkanLoader.cpp:247 E[Video]: (WaitForCommandBufferCompletion:278) vkWaitForFences failed: (2: VK_TIMEOUT)
// Instead of
15:45:154 VideoBackends/Vulkan/VulkanLoader.cpp:247 E[Video]: (WaitForCommandBufferCompletion) vkWaitForFences failed: (2: VK_TIMEOUT)
```
Set the Render Window as the parent of the Confirm On Stop confirmation
dialog when Keep Window On Top is enabled, ensuring it will always be
visible.
Previously, when Confirm On Stop and Keep Window On Top were both
enabled the Confirm On Stop dialog could be hidden by the render window
in the following situations:
* Clicking Stop in the Main Window
* Clicking the Main Window's close button
* Pressing the Stop hotkey while in FullScreen mode
This was particularly troublesome because the confirm dialog is modal,
preventing the user from moving the render window out of the way if it
was obscuring the dialog.

A vector of length 0 can have a null data pointer, which causes UB when
passed to memcpy, so only copy when we actually have data to copy. This
caused crashes in certain cases when compiling Dolphin with Clang and
LTO enabled.
Allow connecting or disconnecting multiple Wii Remotes simultaneously
instead of only handling the highest index whose hotkey is pressed. This
allows using a single hotkey to toggle multiple remotes.
