T2XX sample: new ar-advanced sample to show map import/export and get/set static node APIs.

[honpong]

This PR responds to TM2-4673 request to update the existing rs-ar-basic.cpp sample for T2xx device. However, instead of adding to an existing sample, this PR adds a new sample called rs-ar-advanced to demonstrate how to use T2xx's relocalization API in AR use case:

• import localization map from raw data file before starting T2xx tracking.
• export localization map to raw data file after T2xx tracking ended.
• command line options to specify raw data file paths for the above map import/export.
• set up a callback to receive relocalization event from the device and action after the event.
• get static node from imported localization map after relocalization event detected.
• set static node before localization map exported.
