Update Thread.cpp

used ChatGPT to implement libraries not imported yet (I'm a very inexperienced developer, just got started with C++ 1 month ago so I'm relying alot on AI)

Thanks for the contribution. Closing for now, for these reasons:

• It doesn't compile: PthreadPrivate has no cancelPending member (core/libs/prx/libkernel/Pthread/src/Thread.cpp:523).
• Even with the member added, nothing reads the flag (scePthreadTestcancel never checks it), so the call would report success without cancelling anything.
• No tests, and the PR template isn't filled in (see CONTRIBUTING.md).
• Thread cancellation is already being implemented in feat(libkernel): implement thread cancellation #1141, so this would overlap.

Feel free to reopen once it builds locally, has a test, and doesn't overlap with #1141 (or help review that one).

Other open pull requests touch the same code. Merging one will break the other, or both implement the same thing. If this one builds on them, list them in Depends on.
