Casey Bodley b10364dc21 cmake: add submodule for utf8proc at v2.2.0
adds utf8proc submodule, needed by the arrow submodule in centos. add a
WITH_SYSTEM_UTF8PROC option that controls whether or not utf8proc is
built from submodule

non-system utf8proc is built as a static library to avoid conflicts with
system-provided libraries

ceph.spec.in sets WITH_SYSTEM_UTF8PROC=OFF until it's available in
centos
