fix: add Apple Silicon support

[Jiacheng787]

On Apple Silicon platforms (such as M1 and M2), the mini_racer library is compiled as armlibmini_racer.dylib instead of libmini_racer.dylib. Using the incorrect library path may cause a runtime exception.

To address this issue, we introduce a runtime check to determine if the current system is running on Apple Silicon. We utilize the sys module to inspect the system's characteristics.

Here's how the check works:

1. We use sys.platform to check the identifier of the current operating system. For macOS systems, the value of sys.platform is 'darwin'.

2. We use sys.maxsize to check the maximum integer value supported by the current Python interpreter. On Apple Silicon devices, due to the 64-bit architecture, the value of sys.maxsize is greater than 2^32.

3. If sys.platform is equal to 'darwin' and sys.maxsize is greater than 2^32, it indicates that the current system is Apple Silicon, and the function returns True. Otherwise, the function returns False.

Here's the code snippet that implements this check:

import sys

def is_apple_silicon():
    return sys.platform == 'darwin' and sys.maxsize > 2**32

By incorporating this check into the library's initialization process, we can dynamically determine the appropriate library path based on the underlying system architecture.

If the is_apple_silicon() function returns True, we use the armlibmini_racer.dylib library path. Otherwise, we fallback to the default libmini_racer.dylib path.

This runtime detection ensures that the mini_racer library is correctly loaded on Apple Silicon systems, preventing potential runtime exceptions caused by using the incorrect library path.

Please note that this workaround assumes that the operating system running on Apple Silicon devices is macOS and that a 64-bit Python interpreter is being used. If these assumptions change in the future, the detection logic may need to be updated accordingly.
