Ilya Tocar 91102bf723 runtime: use bytes.IndexByte in findnull
bytes.IndexByte is heavily optimized. Use it in findnull.
This is second attempt, similar to CL97523.
In this version we never call IndexByte on region of memory,
that crosses page boundary. A bit slower than CL97523,
but still fast:

name        old time/op  new time/op  delta
GoString-6   164ns ± 2%   118ns ± 0%  -28.00%  (p=0.000 n=10+6)

findnull is also used in gostringnocopy,
which is used in many hot spots in the runtime.

Fixes #23830
