{video_,}core/cmake: Remove Werror flags already defined code-base wide 

These flags are already defined in src/cmake.

cmake: Enforce -Wunused-function code-base wise

vulkan_common: Silence missing initializer warnings

vulkan_device: Enable shaderStorageImageMultisample conditionally

Stops us from merging code with unused functions in the future.

If something is invoked behind conditionally evaluated code in
a way that the language can't see it (e.g. preprocessor macros), the
potentially unused function should use [[maybe_unused]].

astc: Make the decoder more robust to invalid data

Silence warnings explicitly initializing all members on construction.

Fix Vulkan initialization on ANV.

Invalid ASTC textures seem to write more bytes here, increase
the size to something that can't make us push out of bounds.

Avoid out of bound reads on invalid ASTC textures.
Games can bind invalid textures that make us read or write out of bounds.

ci/linux: Make Mainline AppImages updateable

yuzu: Remove unused variables in Qt code

Removes two unused variables in out Qt code. In this case the removal of
these two results in less allocations, given std::map allocates on the
heap.

configure_motion_touch: Migrate off QRegExp to QRegularExpression

configure_motion_touch: Prevent use after move in ApplyConfiguration()

touch_engine was being compared against after being moved into the
setter for the engine, so this comparison wouldn't behave properly.

QRegularExpression was introduced in Qt 5 as a better replacement for
QRegExp. In Qt 6.0 QRegExp is removed entirely.

To remain forward compatible with Qt 6.0, we can transition over to
using QRegularExpression.

Fix IP validator error

yuzu: Migrate off of setMargin() to setContentsMargins()

setMargin() has been deprecated since Qt 5, and replaced with
setContentsMargins(). We can move over to setContentsMargins() to stay
forward-compatible with Qt 6.0.

vulkan_device: Remove requirement on shaderStorageImageMultisample

yuzu doesn't currently emulate MS image stores. Requiring this makes no
sense for now. Fixes ANV not booting any games on Vulkan.

cmake: Enforce -Werror=switch and -Werror=unused-variable

Port citra-emu/citra#5666: "Rotate previous log file to "citra_log.txt.old""

vk_fence_manager: Use timeline semaphores instead of spin waits

common/parent_of_member: Replace TYPED_STORAGE define with template alias

Provides the same construct, but makes it obey namespacing.

Rewrite KSynchronizationObject, KConditonVariable, and KAddressArbiter

- This is decoupled from core functionality and used for debugging only.
