Rename {absl => std}::optional in //cc/

Automated patch, intended to be effectively a no-op.

As of https://crrev.com/1204351, absl::optional is now a type alias for
std::optional. We should migrate toward it.

Script:
```
function replace {
  echo "Replacing $1 by $2"
  git grep -l "$1" \
    | cut -f1 -d: \
    | sort \
    | uniq \
    | grep "^ui/" \
    | grep \
      -e "\.h" \
      -e "\.cc" \
      -e "\.mm" \
      -e "\.py" \
   | xargs sed -i "s/$1/$2/g"
}

replace "absl::optional" "std::optional"
replace "absl::make_optional" "std::make_optional"
replace "absl::nullopt" "std::nullopt"
replace "absl::in_place" "std::in_place"
replace "absl::in_place_t" "std::in_place_t"
replace "\"third_party\/abseil-cpp\/absl\/types\/optional.h\"" "<optional>"
git cl format
```
