Change input field of compiler path to editable drop-down list. This list will show detected compiler paths.

Verified UI on Linux and Mac

Can you normalize the / and \\ in the dropdown list of compilers? Maybe using the "C_Cpp.preferredPathSeparator"?

Can you increase the top margin in the dropdown? It seems too little top margin in the screenshot.

I left some comments.

Styling the dropdown is not straightforward. Haven't been able to figure out it. Will need to research and look into VS Code repo. The dropdown style is the same on the existing dropdowns.

Isn't it just the style margins or something? I remember changing some of the margins with other UI a few weeks ago. Oh, looks like the existing dropdowns have the same issue, i.e. we've shipped like this already...I just never noticed.

The HTML select and option elements cannot be styled the same way as the other elements. The style depends on the OS, and requires more than CSS to modify the native style. As the current native style works for now, we can change the style later to look like VS Code after we've put in more features/functionalities on the config UI.
