Merge #19131: refactor: Fix unreachable code in init arg checks
eea81146571480b2acd12c8cd7f36b04d056c47f build: Enable unreachable-code-loop-increment (Jonathan Schoeller)
d15db4b1fc988736b08c092d000ca1d1ff686975 refactor: Fix unreachable code in init arg checks (Jonathan Schoeller)
Pull request description:
Closes: #19017
In #19015 it's been suggested that we add some new compiler warnings to our build. Some of these, such as `-Wunreachable-code-loop-increment`, generate warnings. We'll likely want to fix these up if we're going to turn these warnings on.
```shell
init.cpp:969:5: warning: loop will run at most once (loop increment never executed) [-Wunreachable-code-loop-increment]
for (const auto& arg : gArgs.GetUnsuitableSectionOnlyArgs()) {
^~~
1 warning generated.
```
https://github.com/bitcoin/bitcoin/blob/aa8d76806c74a51ec66e5004394fe9ea8ff0fac4/src/init.cpp#L968-L972
To fix this, collect all errors, and output them in a single error message after the loop completes. This resolves the unreachable code warning, and avoids popup hell that could result from outputting a seperate message for each error or warning one by one.
