ETAS pitch for Time module

[mikehaller]

This PR contains the initial code contribution from ETAS regarding the TIME module.

Contents:

• Time Synchronization API / Library (C++)
• Time Synchronization Daemon
• ptp Daemon
• Basic example in C++
• Unit Tests
• Coverage (Lines: 96.8 %, Branch: 72.9 %)

Notes: The build has been migrated to Bazel and C++ code is reusing S-Core baselibs. The ptpd source is C code and a modified version of https://github.com/ptpd/ptpd to support an AutoSAR-profile. One of the default features requires the installation of libcap, but can be disabled during build.

Copyright / License: We keep the ETAS copyright during the pitch phase until the decision by the S-Core architecture community to accept the contribution has been made.
