[wperf] Enhance PrettyTable so it supports multi-row per item as well as items being of the type PrettyTable.

Everton Constantinorequested to merge
everton.constantino/windowsperf:new_prettytable into main

Implements https://linaro.atlassian.net/browse/WPERF-561

This change in itself is already too complex. This is going to support disassembly at a later MR.

  • I changed PrettyTable's m_table map to support a std::variant instead of the usual vector of strings. With this I can add the possibility of items being PrettyTables in themselves.
  • I also needed to enable items to occupy more than a single row, so the infrastructure to calculate row lengths based on items was added.
  • Printing got more complex because. It is now broken down into printing one line at a time, this facilitates recursively printing tables as elements.

This is a result from a standalone version

Unfortuantely for now there isn't much testing that can be done on this feature beyond what we already do with Python. We will be able to enhance this once disassembly gets merged.
