TODOs for Merging with alice Branch and Codebase Cleanup

[Yaxuan-w]

Description:

This issue is created to track the necessary tasks for merging the alice branch and performing general codebase cleanup.

TODOs:

1. Merging with alice branch

• Remove example_grate folder and replace it with fdtables.

2. Codebase Cleanup:

• Delete unused code lines (commented-out lines), specifically in:
  - interface
  - safeposix_rust

3. Porting RustPOSIX Testsuite:

• Ensure the RustPOSIX testsuite is successfully ported: including troubleshooting -> fixing -> documentation for all kinds of changes and differences. I've already made some progress of this and documented on RawPOSIXIssueTrack on my own repo. Need to find a more efficient way for further collaboration.
