perform logging in `CmdLineParser` through an interface (#5478)
This is in preparation of avoiding accessing `std::cout` directly as
well as streamlining and improving the logging during the settings
parsing. There are no functional changes yet.

utils.h: added `startsWith()` and started using it (#5381)
This makes the code much more readable. It also makes it less prone to
errors because we do not need to specify the length of the string to
match and the returnvalue is clear.

The code with the bad returnvalue check was never executed and I added a
test to show that.

fixed #11910 - removed Visual Studio x86 targets from project files and builds from CI (#5397)
Windows XP Pro x64 was released on April 25, 2005 and consumer
processors supporting x86-64 have been around almost as long. Although
there are still 32-bit Windows images available there is not much of a
point maintaining support for these. We also never did any x86 builds
for non-Windows platforms in CI so we don't even know if we work on
those. You might still be able to build 32-bit binaries via CMake.

report `internalError` when command execution returns errorcode / also some related cleanups and tests (#5037)
Encountered while investigating https://trac.cppcheck.net/ticket/11708.

This has been like this since the introduction of `internalError` in
b6bcdf2936 (almost ten years ago to the
day). Logging internal errors which bail out(!) of the analysis simply
to `std::cout` for them possibly never to be seen (and also not affected
the exitcode) is pretty bad IMO. They should always be visible.

I also removed the filename from the message as it is already available
(and thus redundant) and its existence should be defined by the
template.

sped up `Tokenizer::dump()` (#5009)
Scanning the `cli` folder with `DISABLE_VALUEFLOW=1` `Tokenizer::dump()`
will consume almost 25% of the total Ir count when an addon is
specified. This is mainly caused by the usage of `std::ostream`.

qt library: Make Q_PROPERTY a variadic macro to avoid preprocessorErrorDirective (#5370)
Treat Q_PROPERTY as variadic macro to avoid preprocessorErrorDirective
with associative container templates itroducing a "," like for example
`QHash<QString, int>`. Using templates is totally fine in the context of
a moc compiler.

The macro Q_PROPERTY is defined as variadic in
qobjectdefs.h/qtmetaobject.h when not compiling using the moc compiler.

See following references:

This was introduced in #5279. We were transferring the terminating `\0`

directly writing into a `std::string` these extra characters will now
show up in it. So just get rid of them.

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.

-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.
