For host-generated *.oat files, generate a SHA-1 build ID based on the file content and write it to .note.gnu.build-id ELF section. This should allow various developer tools like profilers correlate the data captured for files like boot.oat on the device with the corresponding known version of the file during an offline analysis. Test: Verified that boot.oat contains the build ID section now. Test: make test-art-host Bug: 31292208 Change-Id: Iee48e437009488f20995e73868d5059d349701c0
