C++20 deprecates capturing the this pointer via the '=' capture.
Instead, we replace it or extend the capture specification.

* ipc: Allow all trivially copyable objects to be passed directly into WriteBuffer

With the support of C++20, we can use concepts to deduce if a type is an STL container or not.

* More agressive concept for stl containers

* Add -fconcepts

* Move to common namespace

* Add Common::IsBaseOf

screenshots: Option to save screenshots immediately in a specified directory + Linux workaround

cpu_manager: Remove redundant std::function declarations

yuzu/main: Remove redundant usages of QStringLiteral("")

compatible_formats: Add missing header guard

surface_params: Replace questionable usages of the comma operator with semicolons

game_list: Add "Remove" context menu

Fixes an access violation where the file no longer exists at the specified path while being parsed.

Hides the following options when the title id is 0:
- Open Save Location
- Open Mod Data Location
- Open Transferable Shader Cache
- All removal options except Remove Custom Configuration

Adds the following actions:
- Remove Installed Update
- Remove All Installed DLC
- Remove Shader Cache
- Remove Custom Configuration
- Remove All Installed Contents

device_memory: Remove unused system member

configure_graphics: Remove Force 30 FPS mode

The introduction of multicore rendered this setting non-functional as timing code was changed.

This removes the setting entirely.

This isn't used by anything in particular, so it can be removed.

core_timing: Make use of uintptr_t to represent user_data

We can just return the function directly. Making for less reading.

qt_themes: Set QLabel background color to transparent for Dark and Midnight Blue themes

Makes the interface future-proofed for supporting other platforms in the event we ever support platforms with differing pointer sizes. This way, we have a type in place that is always guaranteed to be able to represent a pointer exactly.

An empty QStringLiteral can more efficiently be replaced with an empty
QString.

vulkan: Resolve -Wmissing-field-initializer warnings

AM: GetDesiredLanguage: remove unused variable

video_core/gpu: Correct the size of the puller registers

GCAdapter: only join worker thread if running & joinable

The puller register array is made up of u32s however the `NUM_REGS` value is the size in bytes, so switch it to avoid making the struct unnecessary large. Also fix a small typo in a comment.

Solves an issue with restoring the value upon reloading program.

nvflinger: Use return value of Lock()

udp/client: Remove unused boost include

virtual_buffer: Mark size parameter of FreeMemoryPages() as [[maybe_unused]]

gc_adapter/gc_poller: Resolve compiler warnings

yuzu/configure_debug: Remove duplicated checkboxes

Those are already found in the Filesystem tab.
They were added back to the Debug tab by mistake in the Vulkan PR.
