This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated. The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.
This is part of an effort to migrate from llvm::Optional to
std::optional:

ConstantOp uses `%idx<value>` and BoolConstantOp uses true/false, which
is similar to the printing for arith::ConstantOp.
