Alex Dale 6bc69d5005 Remove CORE_UTIL_EXPORT
[ Merge of http://go/wvgerrit/155070 ]

These functions are internal utilities and should not be exported from
our library.  IIRC, this was added to aid in Windows tests, but this is
no longer needed.

Bug: 236317198
Test: build_and_run_all_unit_tests.sh
Change-Id: I19beb35a15f0f87dc8f968e1dd5302aed9463e54
