Adding windows support for `pyodide venv`

[ryanking13]

This issue is to track the state of the Windows support for pyodide venv. Currently, it works only in Unix compatible environment.

• Add Windows batchfile wrapper for Pyodide python CLI (Add python CLI script for Windows pyodide#6012)
• Replace all linux-specific path to be universal (Update pyodide venv logic to support Windows platform #264)
• Remove make dependency (Add fallback method for parsing Makefile.envs #266)
• Handle EBADF: bad file descriptor, fsync error in windows (Handle EBADF error during fsync when the runtime exits pyodide#6018)
• (Optional) Refactor the venv.py to be more extensible
