Bug 40595 (and others): The big MR for 102

This MR moves Tor Browser to the first Firefox 102 branch, updates all the needed toolchains, and tries to remove the dependency on GCC on Windows whenever possible.

Fixes: #29318 (closed), #29321 (closed), #29322 (closed), #40409 (closed), #40591 (closed), #40592 (closed), #40595 (closed), tor-browser#41152 (closed).

Currently drafted because blocked on !501 (merged) (it includes also its commit, but in case of change I'll rebase it to main).

requested review from @boklm

Err, there's one error for sure: we should reuse LLVM also for Android.

Parallel compilation of NSIS failed on my machine.

Initially I thought of disabling it again, but since I've managed to recover from the error, I've decided to silence the errors from the parallel run and run it again sequentially, instead.

A cypherpunk noticed that we could remove llvm-mingw, because we don't use its wrapper anymore.

We shouldn't merge libc++, libc++abi and libunwind anymore, see tor-browser#41152 (closed).
