clang-tidy modernize-use-auto check.

clang-tidy modernize-use-override check.

clang-tidy modernize-use-equals-default checks.

clang-tidy modernize-use-default-member-init check

clang-tidy bugprone-macro-parentheses check.

The direct initialization with parentheses does not compile
with explicit Polygon constructor. The direct list initialization
considers both, the explicit and non-explicit constructors.

Avoids an implicit conversion to Vector3 of both arguments.

Also those where the second and so forth arguments are defaulted.

The MathLib::TemplateVector3 is an exception, because of the many
required changes through the code, which relies on the implicit
conversion from TemplatePoint<T, 3> to TemplateVector3<T>.

clang-tidy '*explicit*' check.

Removed include-what-you-use for the moment as it segfaults.

Cleanup _MSC_VER uses.

The upstream fixes the visual studio compilation errors.

The enclosed code depends on OS, not compiler.

[[noreturn]] attribute is supported by now.

Cleanup cmake output

Add domain of definition for parameters.

Move the renamed VariableDependentNeumann BC docu.

Together with the string to enum converters.

These are almost the same and the difference is in the
handling of the shape functions.

See disabled-tests.log

Speeds up CMake run significantly and reduces Conan output a lot.

Helps to identify that not everything was built. Prevents empty
artifacts when browsing to
https://jenkins.opengeosys.org/job/ufz/job/ogs/job/master/lastSuccessfulBuild/artifact/

Jenkins link should update on each build but somehow netlify does
not invalidate the cache for it... Only manually deleting the cache
worked so I temporarily set
https://jenkins.opengeosys.org/job/ufz/job/ogs/job/master/lastSuccessfulBuild/artifact/
as the download link.

Fix cppcheck warnings.
