Kazu Hirata 1a36588ec6 [mlir] Use std::nullopt instead of None (NFC) 
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:
