Revert of Revert of Add CPP API for BLE advertisments. (patchset #1 id:1 of https://codereview.chromium.org/1111563002/)

Reason for revert:
Can't seem to find any bots this was failing on. Trybots on the original CL that had component=shared_library are working fine and locally it builds fine too.
