ports: add webkitgtk

[Andy-Python-Programmer]

Todo

• [ ] Update the Rust fork
• [x] Upgrade LLVM
• [x] Upgrade Rust
• [x] Port jq
• [x] Port WebKitGTK
• [ ] Implement Ext2::truncate()
• [ ] Implement getsockopt()
• [ ] Implement setsockopt()
• [x] Have a look at the mmap failure. Apparently, WebKit makes use of mmap instead of mprotect to change the protection flags of the guard pages. The syscall fails with EFAULT but should be fine for now since it does not check for failure. Checkout https://github.com/WebKit/WebKit/blob/main/Source/WTF/wtf/posix/OSAllocatorPOSIX.cpp#L106C2-L109C22
• [ ] Call to pthread_getattr_np with unset stackAddr and stackSize is problematic since it internally calls get_own_stackinfo which is reliant on /proc/self/maps, which does not exist. Checkout https://github.com/managarm/mlibc/blob/ffea4f0cf708dc1a96528bf3cfa19fb2bbc75d24/options/posix/generic/pthread-stubs.cpp#L267C1-L294C1
• [ ] If you do get it running, first of all good job. Your past self is proud of you. Do not forget to push the mlibc changes as-well.

Debugging Notes

• Thread Names and Functions:
  • NetworkProcess: Responsible for handling network requests and storage management. All WebContent processes in a single session (default vs. private browsing) share a single networking session in the networking process.

The webpage does not load yet, but we have some progress :^)

Today's Debugging Notes:

WebPageProxy -> m_process -> WebProcessProxy -> WebProcessPool

Find why the process is not receiving the UNIX IPC messages sent.

Now kernel backtraces resolve userland address:

mlibc tags the memory location using sys_tag.

In addition, now systraces for syscalls that take in a file descriptor are more readable since now they print out the file path as-well.

Today's Debugging Notes:

• Ancillary Data - Unix Sockets - Have a look in static ssize_t readBytesFromSocket(int socketDescriptor, Vector<uint8_t>& buffer, Vector<int>& fileDescriptors)

The mmap(2) silent failure memes have now been resolved.

I am merging this pull request, even though its not fully functional yet. The pull request adds other stuff that fixes stuff in master and I cannot be bothered to cherry pick the commits on top of master.
