x86: Unifies 'strlen-evex' and 'strlen-evex512' implementations.
This commit uses a common implementation 'strlen-evex-base.S' for both
'strlen-evex' and 'strlen-evex512'
The motivation is to reduce the number of implementations to maintain.
This incidentally gives a small performance improvement.
All tests pass on x86.
Benchmarks were taken on SKX.

Geometric mean for strlen-evex512 over all benchmarks (N=10) was (new/old) 0.939
Geometric mean for wcslen-evex512 over all benchmarks (N=10) was (new/old) 0.965
Code Size Changes:
strlen-evex512.S : +24 bytes
wcslen-evex512.S : +54 bytes
