String: Add overflow tests for strnlen, memchr, and strncat [BZ #27974]
This commit adds tests for a bug in the wide char variant of the functions where the implementation may assume that maxlen for wcsnlen or n for wmemchr/strncat will not overflow when multiplied by sizeof(wchar_t). These tests show the following implementations failing on x86_64: wcsnlen-sse4_1 wcsnlen-avx2 wmemchr-sse2 wmemchr-avx2 strncat would fail as well if it where on a system that prefered either of the wcsnlen implementations that failed as it relies on wcsnlen.
