Factoring GUID generation from metrics to base
Factors GUID generation into base/rand_util. The Autofill feature is in need of this utility so am factoring GUID generation out of metrics and moving to the commons.
BUG=58813
TEST=RandUtilTest.GUIDGeneratesAllZeroes, RandUtilTest.GUIDGeneratesCorrectly, RandUtilTest.GUIDCorrectlyFormatted, MetricsServiceTest.ClientIdCorrectlyFormatted
