Use QString::fromLatin1() less to avoid string allocations
QString::fromLatin1 always allocates memory, but there are
cases where we can avoid/reduce allocations or/and reduce
text size, e.g.:
QStringBuilder expressions
Fix: replace QString::fromLatin1 with QL1S
QString::fromLatin1().arg(String) pattern
Fix: replace with QStringBuilder
Overloaded functions with QL1S arg
Fix: replace QString::fromLatin1 with QL1S
In rare cases if there is no overloaded function
with QL1S and we have deal with string literal,
replace QString::fromLatin1 with QStringLiteral.
