x86/cpufeatures: Add WBNOINVD feature definition
Add a new cpufeature definition for the WBNOINVD instruction.
The WBNOINVD instruction writes all modified cache lines in all levels of
the cache associated with a processor to main memory while retaining the
cached values.
Both AMD and Intel support this instruction.
