input_common: Support SDL toggle buttons

gl_texture_cache: Workaround slow PBO downloads on radeonsi

uuid: Directly compare UUID instead of checking per element

There's an optimization bug on non-git mesa versions where not
specifying GL_CLIENT_STORAGE_BIT causes very slow reads on the CPU
side.

Add this bit for all vendors.

We can now update this for C++20

- value return can be different 0, is not error is normal, error is only -1.

This ensures that Qt positions the render window at the correct position on initializing the respective render backends.

Adds support for loading games with multiple programs embedded within such as the Dragon Quest 1+2+3 Collection

On the texture cache we handle multisampled images by keeping their real
size in samples (e.g. 1920x1080 with 4 samples is 3840x2160).

This works nicely with size matches and other comparisons, but the
calculation for guest sizes was not having this in mind, and the size
was being multiplied (again) by the number of samples per dimension.
For example a 3840x2160 texture cache image had its width and height
multiplied by 2, resulting in a much larger texture.

Fix this issue.

- Fixes performance regression on cooking related titles when an
  unrelated bug was fixed.

Images used as render targets were not being "prepared", causing
desynchronizations on the texture cache. Needs #6669 to avoid
performance regressions on certain cooking titles.

- Fixes black shadows on Age of Calamity.

cmake: Be more specific with Qt

input_common: Fix mouse panning behaivour

The original language "not implemented" is wrong if the implementation
exists but is not compiled. This causes a bit of a debugging headache
when it goes wrong. Log it if the window manager is known before
exiting.

On Linux, due to the way we include SDL2 as a submodule, it makes it
difficult for us to specify which SDL_config.h we intended to include.
Before, CMake would default to the dummy one included with SDL and
ignore the generated one.

This tells CMake to use the generated one. In addition, we define
USING_GENERATED_CONFIG_H to throw an error in case the dummy config is
used by accident. Fixes Vulkan not working on Linux yuzu-cmd.

configure_audio: Fix volume clamping to 0

Many settings in common/settings.h are missing from yuzu-cmd, either
they were added to default_ini.h but not read in, or vice versa, or the
setting was altogether omitted from yuzu-cmd. Some defaults were
reported wrong, so those were fixed where noticed.

When YUZU_USE_BUNDLED_QT was specified on a system with a compliant Qt
version installed, CMake configuration would cause an error due to
mixing YUZU_USE_BUNDLED_QT with the system Qt.

Solution is to only search for Qt when YUZU_USE_BUNDLED_QT is disabled.

As-is causes issues with building yuzu using MinGW GCC on Linux-based
machines. Only set the variable when needed. (I'm not quite sure how
this was working before.)
