perf: add a faster skip_until using SIMD memchr

it was put under the "memchr" feature-flag, as memchr SIMD support
is only on x86_64 at the moment (json bench is ~8% faster over baseline there):
pest-parser#737 (comment)
once memchr has the Arm SIMD support, this could be perhaps the default
implementation.
For Aho-Corasick, it'll require more investigation.
