Enable tvOS and watchOS (#147)

I realized that we need this when I was building the OpenXLA/IREE runtime for tvOS and watchOS.

1. Before this change, the `CMakeLists.txt` file uses CMake built-in variable `IOS`, which is equivalent to `CMAKE_SYSTEM_NAME STREQUAL "iOS"`, to tell if it is building for Apple mobile platforms. This trick prevents CMake from recognizing tvOS and watchOS.

   Introduce `IS_APPLE_OS` variable which is true if `CMAKE_SYSTEM_NAME MATCHES "^(Darwin|iOS|tvOS|watchOS)"`.

2. Before this change, the `CMakeLists.txt` assumes that Apple's ARM64 platform has the name "arm64". However, M2 chip has the name "arm64e". This pull request changes `MATCHES "arm64"` into `MATCHES "arm64.*"`.
