add vscode applications to the predefined IDEs for "Open in Editor"

[GitMensch]

@dfaure may want to have a look at this, too, as he added the call to the code binary

• added vscodium
• have both vscode applications also available on Windows + MacOS

Question: Is it fine to push the suggested formatting change?

-    {"codium", "-g %f:%l:%c", QT_TRANSLATE_NOOP("MainWindow", "VSCodium"), "codium"}
-};
+    {"codium", "-g %f:%l:%c", QT_TRANSLATE_NOOP("MainWindow", "VSCodium"), "codium"}};

And just a note to people interested - this also works fine when running HotSpot on remote environments when started from vscode terminal (both on WSL and SSH remotes).

Yes please apply the clang-format fix as well.
