Fix -Wbitwise-instead-of-logical on clang-cl-14

[jelmansouri]

The current code trigger a clang-cl warning when we moved to LLVM 14.

@Jake-Shadle, @repi, did Embark move to LLVM 14 yet?
Also I noticed that some other fixes were done directly on this repo 4.1 branches if you want me to try to upstream them first please tell me!

[repi]

thanks!

@jelmansouri yes we are on Rust 1.60 which I believe includes LLVM 14, haven't seen this warning though when building through physx-rs. not sure why.

upstreaming to Nvidia repo unfortunately seems a bit hopeless, they haven't merged most fixes. So think merging in here and updating physx-rs would work. though feel free to attempt a PR on the Nvidia repo, maybe you'll have more luck with it!

@hrydgard added you here as you are codeowner on physx-rs and we don't have anyone else on this fork repo

The update of the C++ compiler is separate in our case, we can use 1.60 that uses LLVM 14 for codegen, but still rely on the a clang/LLVM 13 for linking and compiling any C++ code (or GCC for that matter). The issue started only when moving the C++ compiler to LLVM14 since I try to keep them in sync.
