x86: Unifies 'strnlen-evex' and 'strnlen-evex512' implementations.
This commit uses a common implementation 'strnlen-evex-base.S' for both
'strnlen-evex' and 'strnlen-evex512'
This patch serves both to reduce the number of implementations, and it also does some small optimizations that benefit strnlen-evex and strnlen-evex512.
All tests pass on x86.
Benchmarks were taken on SKX.
