The allocation invokes some heavy ValueFlow computations. We just want
to generate an unconditional error from the analysis so use some lighter
code which does the same.
`TestThreadExecutorFiles::deadlock_with_many_errors`
Before:
```
real 0m23.517s
user 0m33.453s
sys 0m2.297s
```
After:
```
real 0m5.051s
user 0m6.234s
sys 0m0.422s
```
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`
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.

* SingleExecutor: added TODOs
* test `SingleExecutor` with files and project
* SingleExecutor: process markup files after code when scanning project
* TestSingleExecutor: generate scoped files before calling executor
* CI-unixish.yml: added `--output-on-failure` to CTest call
* helpers.cpp: improved error reporting in `~ScopedFile()`
* use unique filenames in executor tests to avoid collisions
* fixed `functionStatic` selfcheck warnings
* added `Settings::useSingleJob()` and use it instead of checking `jobs` or `jointSuppressionReport`
* extracted single job execution into `SingleExecutor`
* moved `reportStatus()` from `CppCheckExecutor` to Èxecutor
* TestSingleExecutor: improved tests
* added testing of markup extension handling in executors
* cleaned up includes based on `include-what-you-use`
* testsingleexecutor.cpp: suppress `performance-unnecessary-value-param` clang-tidy warnings
* ProcessExecutor: send color via pipe instead of applying it beforehand
* do not unconditionally apply colors to output / disable all colors in tests / adjusted tests for changed output behavior
* fixed precision loss in `Executor::reportStatus()`
* fixed `naming-varname` selfcheck warnings
* iwyu.yml: use debian:unstable to always get latest include-what-you-use
* cleaned up includes based on include-what-you-use
* mitigated include-what-you-use false positives
