Dependency's platformFilter feature should support other platforms other than iOS and macOS

[ikesyo]

Since Xcode 14, multi-platform targets are supported not only for iOS and macOS (Mac Catalyst) but for watchOS, tvOS and visionOS additionally.

Xcode 14 enables a single target to support multiple platforms and conditionally include dependencies, code, resources, and build settings for specific platforms. (74664328)

So the feature should not be limited to Mac Catalyst and should be updated to support other platforms.

  Line 604 in 2cf88e8

  - [ ] **platformFilter**: **String** - This field is specific to Mac Catalyst. It corresponds to the "Platforms" dropdown in the Frameworks & Libraries section of Target settings in Xcode. Available options are: **iOS**, **macOS** and **all**. Defaults is **all**.

• XcodeGen/Sources/ProjectSpec/Dependency.swift

  Lines 49 to 53 in 2cf88e8

  	public enum PlatformFilter: String, Equatable {
  	case all
  	case iOS
  	case macOS
  	}

destinationFilters is the newer one for Xcode 14+ with support for all platforms, use that instead of platformFilter
