gRPC has been having the wrap_memcpy workaround to handle the breaking change of memcpy on glibc 2.14 (ref1, ref2). This was necessary to build more portable artifacts which are expected to run on most linux distributions and we manged to have #5007 years ago for this.

Since we started to use manylinux2010-based docker images for artifacts, however, this became unnecessary since CentOS 6 has glibc 2.12 which is older than 2.14 so it doesn't have memcpy issue, which is another benefit of using manylinux2010.

Superseding #23385
Changes after the original PR was made; Ruby is using manylinux images (manylinux2014) enabling this change, no more old docker images in our test env.

one nit on the description: ruby builds off manylinux2014 images now, (but I believe that shouldn't change anything)
