Shared library track event: API/ABI to emit data

This commit implements:
* New ABIs to emit events to the data source:
  * A low level ABI that allows users to do their own message
    serialization.
  * A high level ABI that accepts a representation of the data to be
    traced and performs serialization in the library.
* The PERFETTO_TE macro (similar to the TRACE_EVENT macro) that can be
  used to emit trace events using the high level ABI.
