This PR rearranges things in the CMake system to make compiling with Qt6 possible

1. Camera API has changed in Qt6, so the camera feature is disabled
2. A previous fix involving QLocale is now version gated.
3. QRegExp replaced with QRegularExpression, see #5343
4. Qt6_LOCATION option added to specify a location to search for Qt6
  (see examples below)
5. windeployqt is used to copy Qt6 files into the build directory on Windows

Notes for Arch Linux
Arch install happened to have qt6-base qt6-declarative qt6-translations installed

mkdir build && cd build
cmake .. -GNinja -DYUZU_USE_BUNDLED_VCPKG=ON -DYUZU_TESTS=OFF -DENABLE_QT6=YES -DYUZU_USE_BUNDLED_QT=NO

Windows (MSVC)
Qt wants users to download precompiled libraries via an online installer,
it is worth noting that the GPL/LGPL takes precendence over any ...

In the Qt Maintenance tool, under a version, such as 6.3.1
Select "MSVC 2019 64-bit"
Under Additional Libraries Qt Multimedia may be of use for Camera support

For the Web Applet I had to select the following:
PDF Positioning WebChannel WebEngine

mkdir build && cd build
cmake -G "Visual Studio 16 2019" -DQt6_LOCATION=C:/Qt/6.4.0/msvc2019_64/ \
-DENABLE_COMPATIBILITY_LIST_DOWNLOAD=YES -DYUZU_USE_BUNDLED_QT=NO \
-DENABLE_QT_TRANSLATION=YES -DENABLE_QT6=YES ..

Some numbers for reference (msvc2019_64)
Qt5 (slimmed down) 508 MB
Qt5.15.2 all in    929 MB
Qt6.3.1           1.71 GB
Qt6.3.2           1.73 GB
Qt6.4.0-beta3     1.83 GB
Qt6.4.0           1.67 GB

Gating the IR Sensor code behind a macro like so
`#if (QT_VERSION < QT_VERSION_CHECK(6, 0, 0)) && YUZU_USE_QT_MULTIMEDIA`

The YUZU_USE_QT_MULTIMEDIA flag is implemented in later commit

Also the locale fix in src/yuzu/main.cpp is now gated against Qt6,
as it causes compilation error

The border adds its own width at least on Linux which causes the icon to
be offset by 1px, and cropped by 2px on the bottom and right sides.

A hopefully more informative dialog that most importantly notifies the
user that their saves will be deleted with the user profile.

Visual Studio has an option to search all files in a solution, so I
did a search in there for "default:" looking for any missing break
statements.

I've left out default statements that return something, and that throw
something, even if via ThrowInvalidType. UNREACHABLE leads towards throw

R_THROW macro leads towards a return
