Support Windows Platform

[NingLi670]

Three changes make AndroidWorld runnable on Windows operating system:

• Change the hard-coded path /tmp to automatically obtain it according to the operating system.
• Change most os.path.join into str(Path(*args).as_posix()) to adapt to the path in posix format.
• Add strip() to deal with \r in Windows platform.

More changes you need to do to make it work on WIndows Platform:

• Changes in AndroidEnv: Install a11y forwarding apk from filesystem google-deepmind/android_env#265
• Instead of ~/Library/Android/sdk/emulator/emulator, start the emulator.exe from another path. Usually it is ~\AppData\Local\Android\Sdk\emulator\emulator.exe.
• Manually specify the adb path and disable _find_adb_directory in minimal_task_runner.py and run.py.
• Disable _increase_file_descriptor_limit in env_launcher.py.

Have you check that this worked on unix-based environments as well? I will try and confirm that it does before merging this

Sorry, I haven't check it on unix-based environments. It will be great if you can do this.
