Fix 11579: false negative: knownConditionTrueFalse with non-bool as bool parameter (#5349)
This adds a new checker to check for pointer to bool conversions that
are always known. I removed the previous knownConditionTrueFalse checks
since this was too noisy.

removed unnecessary `Settings` parameter from `Check::runChecks()` and made `Tokenizer` a reference (#5308)
There was no need for the `Tokenizer` parameter to be a pointer as it
could never be `nullptr` and was also dereferenced without checking
first.

As a reference to the `Settings` was already available via the
`Tokenizer` there was no need to pass it separately. In the production
code there will only be one instance of it but in the tests we could
have accidentally passed a different one.

CmdLineParser: deprecated `--template <template>` and `--template-location <template>` (#5331)
Both are bugprone since they just take the next parameter which doesn't
start with `-`.

Also `--template` has not been documented since
17842394c0 back in 2011(!). And
`--template-location` has never been documented since its induction in
f058d9ad08. That's also why we can have a
short deprecation period.

fixed #6316 (Use std::to_string() in place of MathLib::toString() ...) - deleted default implementation of `Mathlib::toString()` (#5341)
It was also used inconsistently and seemed to imply there is some
special handling which wasn't the case. It was just an alias for
`std::to_string()` for non-`double` types. So there was no need for it.

-j 0 causes indefinite hang. require >= 1 (#5326)
In cppcheck 2.11.1 (macOS), using `-j 0` actually causes cppcheck to do
nothing–it stalls indefinitely.

I could only find one place where `mSettings.jobs` was validated against
> 0 and it's simply an assert, so you wouldn't hit it in a release
build.

- Require -j >= 1 
- Cap -j at 1024, not 10000  (I don't even know what would happen if
you created 10,000 threads, but nothing good; likely exhaust virtual
memory or grind the process to a halt). 1024 is still obscene but there
may be some hypercomputers out there that have that many logical cores.

Check if --cppcheck-build-dir exists (#5254)
Cppcheck does not report that cppcheck build dir does not exist and also
does not report any write issues to the non-existent directory.

This means that cppcheck build dir is actually not used.

We should either create the directory or fail.

testrunner: use structs with designated initialization to pass options (#4975)
I need to add parameters to some `check()` functions in the tests and
things are already pretty messy with having to specify all the default
values - readability aside.

I found this on https://stackoverflow.com/a/49572324/532627 - apparently
the CC BY-SA license by StackOverflow allows the usage within GPL.

This is a mess. The version is AUR is still outdated and also doesn't
install anymore. Fedora 38 carries the latest version of it so use that
now. Keep the old steps in case we need to switch again in the future.
