Add build support for gcc-11, gcc-12 and gcc-13

[bjosv]

Handle build-warning errors by disabling some warnings found by the new compiler versions.
Additionally fix a new overloaded-virtual warning found by gcc-13.

The issues can be found in logs on local CI-runs:
gcc-11 maybe-uninitialized warning:
https://github.com/Nordix/trex-core/actions/runs/7259509593/job/19776795795

gcc-12 dangling pointer warning:
https://github.com/Nordix/trex-core/actions/runs/7259509593/job/19776796061

Run with similar corrections, which are ok:

The Jenkins job fail while generating some kind of HTML report:
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 1480: ordinal not in range(128)

I cant see what it does, but speculating that its because of the character ö in my name..

Updating the xmls2html.py script with error replacement could help:

>>> b"\xc3".decode("ascii")
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128)

>>> b"\xc3".decode("ascii", errors="replace")
'�'

What is your recommendation @hhaim, should I update the commits in this PR so there are no non-ascii characters?
