Improve testcases for unsigned char platforms (#5524)
I got error messages while building `cppcheck 2.12.0` for RISC-V Arch
Linux:
```
Testing Complete
Number of tests: 4420
Number of todos: 331
Tests failed: 2

/usr/src/debug/cppcheck/cppcheck/test/testcondition.cpp:4501(TestCondition::alwaysTrue): Assertion failed. 
Expected: 
[test.cpp:6]: (style) Condition 'o[1]=='\0'' is always false\n

Actual: 
[test.cpp:4] -> [test.cpp:6]: (style) Condition 'o[1]=='\0'' is always false\n

_____
/usr/src/debug/cppcheck/cppcheck/test/testcondition.cpp:5014(TestCondition::alwaysTrueContainer): Assertion failed. 
Expected: 
[test.cpp:5]: (style) Condition 'buffer.back()=='\0'' is always false\n

Actual: 
[test.cpp:3] -> [test.cpp:5]: (style) Condition 'buffer.back()=='\0'' is always false\n
```

I found out the reason is that the testcases were designed for
x86/x86_64 or other `signed char` platforms (i.e. default character type
is `signed char` ), whereareas RISC-V is an `unsigned char` platform,
which causes different behavior in
`lib/valueflow.cpp:valueFlowImpossibleValues`. I'm not sure whether this
error leads from a functional bug, so if you have a better approach to
fix it, please let me know.

Maybe you could reproduce this error on x86_64 platform by setting
`defaultSign = 'u';` in `Platform::set(Type t)`.

windows.cfg: Fix wrong FlushConsoleInputBuffer configuration (#5526)
After flushing, the function returns. Before it was configured to
not-return.
A proper regression test was added.

windows.cfg: Fixed wrong configuration of GetModuleHandle(A|W)-functions (#5525)
This fixes a FP: `Variable 'path' can be declared as const array
[constVariable]`

The reason was the wrong direction attribute of GetModuleHandle()

MathLib: renamed `to{U}LongNumber()` to `toBig{U}Number()` (#5503)
The name was misleading as it was actually a `long long` and also if we
ever move to an (optional) 128-bit value it wouldn't even less fitting.
We should name it to match our alias type.

refs #4452 / refs #11705 - improved `--showtime=` behavior and testing (#4876)
This is a step onto leveraging the `ThreadExecutor` implementation for
`ProcessExecutor` which is a follow-up to #4870. We need to have the
proper test coverage and the existing implementations working as
expected before we move to the shared code.

Fixes:
- added `--showtime=` tests for all executor implementations
- only print `--showtime=summary` once at the end
- prevents `--showtime=` by multiple threads to be written at the same
time - essentially breaking the output
- reset the timer results before each test
- deprecated `top5` in favor of `top5_file`
- fixed printing for all executors except `ProcessExecutor`
