Meta: Suppress rule V1076 in PVS-Studio Static Analysis

Browse source 
This rule attempts to flag invisible Unicode characters which would
potentially be used by an attacker to hide code that humans can't see.
https://pvs-studio.com/en/docs/warnings/v1076/

AKA the "Trojan Source" attack: https://arxiv.org/abs/2111.00169

Unfortunately our `LibUnicode` source code contains these hidden
characters as they are part of the Unicode character set that the
library exposes. So we have, and will always have 100s of false
positives.
