Adds substr, find/rfind/find_first_of/find_last_of/find_first_not_of/ find_last_not_of, starts_with/ends_with, and operator[] to string_view_type, mirroring string_type's search/substring surface so script authors can traverse a buffer through string_view without allocating. Sharing method names with string_type creates an ambiguity in dispatch_with_conversions when the script call needs arithmetic conversion (e.g. myString.substr(int, int)): both string::substr and string_view::substr match-except-for-arithmetic, and the existing const/non-const tiebreaker doesn't apply. Extend dispatch_with_conversions to prefer the candidate whose first/receiver parameter type exactly matches the actual receiver, mirroring the deprioritization already in dispatch(). With this in place, myString.substr(1, 2) still resolves to string::substr while mySV.substr(1, 2) resolves to string_view::substr (returning a string_view). Updates the doc comment on string_view_type and adds a compiled test that locks in both dispatch directions plus the new search/substring methods. Requested by @lefticus in PR #697 review.
