bootstat: Refactor init/utils/boot_clock into base/chrono_utils.
Use this for bootstat and init. This replaces the custom uptime parser in bootstat. This is a reland of aosp/338325 with a stubbed implementation for Darwin. This change also has clang_format fixes (automatic). Bug: 34352037 Test: chrono_utils_test Change-Id: I72a62a3ca1ccfc0a4ccc6294ff1776c263144686
