Remove: rdtsc and TIC/TOC based on CPU ticks

[TrueBrain]

Motivation / Problem

Looking over warnings from our CI / Release Job, I keep noticing it warns in some cases that there is no good RDTSC found. But, you need to know, RDTSC is only ever used during development, when adding TIC/TOC statements.

Further more, for a long time now we have a TICC/TOCC alternative, which uses std::chrono. It is not as precise as the RDTSC can be, but I think most of us have been using TICC/TOCC over TIC/TOC, as reporting in ms is much more natural than reports in some arbitrary unit.

Description

Remove RDTSC code, and rename TICC/TOCC to TIC/TOC (which is based on std::chrono).

This has no impact on the user. This is only relevant for developers.
