Add test_strchrnul() and speed_strchrnul(), selected by the new
CONFIG_TESTING_ARCH_LIBC_STRCHRNUL option, covering the hit, miss and
NUL cases.
Sweep alignment 0..7 and the boundary sizes {0, 1, 7, 8, 9, 15, 16, 17,
31, 32, 33, 63, 64, 65, 127, 128, 129, 255, 256, 257} in the scan
function tests (memcmp, memchr, strlen, strcmp, strchr, strncmp,
strnlen, strrchr) and in memmove. Those sizes sit on the 8 and 16 byte
chunk edges and on the sub-word tails, so vectorized (NEON/MVE) and
word-at-a-time implementations are stressed exactly at their alignment
and size boundaries instead of only at "nice" lengths. memmove is
additionally exercised across four overlap layouts: forward, backward,
contained and adjacent.
Impact: test only, selected by CONFIG_TESTING_ARCH_LIBC (default n).
Testing: built and ran qemu-armv7a:nsh (Cortex-A7, generic C
implementation) and sim:nsh on Linux x86_64 (Ubuntu 24.04, gcc 13.3.0)
with CONFIG_TESTING_ARCH_LIBC=y. All 16 enabled functions report
PASSED and "arch_libc_test Passed". These tests pass against the
generic C routines, which establishes the correctness baseline before
architecture optimized assembly is introduced.
