* Fix warning C4068: unknown pragma 'nounroll'
* Fix warning C4068: unknown pragma 'unroll'
* Fix warning C4068: unknown pragma 'clang'
* Fix warning C4305: 'initializing': truncation from 'double' to 'float'
* Fix warning C4267: 'argument': conversion from 'size_t' to 'utils::FixedCapacityVector<filament::uberz::WritableArchive::Material,std::allocator<T>,true>::size_type', possible loss of data
* Fix warning C4267: 'argument': conversion from 'size_t' to 'uint32_t', possible loss of data
* Fix warning C4244: 'initializing': conversion from 'A' to 'T', possible loss of data
* Fix warning C4334: '<<': result of 32-bit shift implicitly converted to 64 bits (was 64-bit shift intended?)
* Fix warning C4293: '>>': shift count negative or too big, undefined behavior
* Fix diagnostic warning C4189: 'channels': local variable is initialized but not referenced
* Use [[maybe_unused]] where possible and revert aa79bd6fa8.
* Revert unary minus for non-MSVC compilers
* Add macro for enabling warnings temporarily
* Get rid of UTILS_HAS_CXX17
