  [NFC][ADT] Tweaked some functions in StringRef

Reduced the usage of variables in the `rfind` and `count` functions.

Replaced calls to `drop_front` with direct use of `substr` in `consume_front`,
since `starts_with` already performs length check on the string. Did the same
for other functions.

Using the `std::clamp` in `slice` makes the code more straightforward.
