feat(cli): configurable iOS build scheme

[imhoffd]

This allows custom scheme names to be used when running npx cap run.

looks good and works fine

but wouldn't it better to make it a param on the run command?
i.e: capacitor run ios --scheme="MyScheme"

Also the scheme name might be a little confusing since we have iosScheme on server object that configures the scheme of the url used to load the app and also the app url scheme for opening the app from another app.

Maybe, but later on we may want to use the build scheme to derive more information about the iOS project for sync, etc. By using xcodebuild -showBuildSettings with the configured scheme, we can get the folder structure of the project and know exactly where everything is, which means developers can rename folders. I also think it will be useful if we ever add the npx cap build command.

I would rather deprecate iosScheme in favor of server.ios.httpScheme (and server.android.httpScheme for Android) to clear up any potential confusion. What do you think?

Then httpScheme name is confusing because you can't really use http value.

Anyway, I approved the changes, just sharing my concerns.

Wow, my brain said urlScheme but I wrote httpScheme.
