### Problem Description

Currently setting `name` or `executableName` in config will change **both** name of output file and the name displayed in the system (docker and toolbar on macOS, taskbar on Windows). We need to make the names in these two use cases different.

### Proposed Solution

Add a `displayName` field to the config. On macOS this value will be set to `CFBundleName` and `CFBundleDisplayName` in `info.plist`. On Windows this value will be set to `FileDescription` field metadata of the executable. This field will fallback to the `name` field if not specified.

### Alternatives Considered

Allow the `extendInfo` config field to override `CFBundleName` and `CFBundleDisplayName` on macOS, like the `win32metadata` config field on Windows. This is the solution described in #387.

### Additional Information

I do not know how to set the display name on Linux. Need more info on this.
