Include wasi-libc project into tor-browser-build

For compiling things to wasm during the build process of tor-browser we need to have a sysroot. The wasi-libc project would provide that one. This ticket reflects Mozilla's https://bugzilla.mozilla.org/show_bug.cgi?id=1582192.

Moving my tickets to December.

The patch in branch gk/bug_32389_v5 looks good to me. I merged it to master as commit e8574bbde076ba917f4d3fd3e71c6c7ee10716c4.

I also opened #33462 (moved) as I see we added one more place where we need a cc -> gcc symlink.
