Add apple platform cross compile workflows.

Xác định các tệp workflow GitHub Actions hiện có trong repository và so sánh các quy ước của chúng với ví dụ Apple CC Matrix được cung cấp. Thêm workflow Apple-platform tương ứng, sau đó xác minh rằng ma trận bao phủ iOS, tvOS, visionOS và watchOS, đồng thời mỗi build/test job đều hoàn tất thành công.

Swift-MMIO wants to make sure it can build for all apple platforms, so we've added the following workflow. Something similar should be provided directly by this repo.

  workflow_call:

jobs:
  apple-cc-build:
    name: ${{ matrix.os.name }} (Xcode ${{ matrix.xcode_version }} - ${{ matrix.macos_version }} - ${{ matrix.macos_arch }})
    runs-on: [self-hosted, macos, "${{ matrix.macos_version }}", "${{ matrix.macos_arch }}"]
    strategy:
      fail-fast: false
      matrix:
        xcode_version: ["16.3"]
        os:
          - name: iOS
            platform: iOS
