        x86-64: Add wcslen optimize for sse4.1
    
    Added wcsnlen-sse4.1 to the wcslen ifunc implementation list and did
    not add wcslen-sse4.1 to wcslen ifunc implementation list. This commit
    fixes that by removing wcsnlen-sse4.1 from the wcslen ifunc
    implementation list and adding wcslen-sse4.1 to the ifunc
    implementation list.
    
    Testing:
    test-wcslen.c, test-rsi-wcslen.c, and test-rsi-strlen.c are passing as
    well as all other tests in wcsmbs and string.
