CMake: Disable Clang 18+ -Wvla-cxx-extension warning

Browse source 
This warning warns about variable-length arrays being a non-standard
extension to the C++ language. We still have a few instances of VLAs, so
let's disable the warning for now.

This does not interfere with `-Wvla`, which we use to completely forbid
this (potentially dangerous) feature in the Kernel and LibCrypto.
