Provide location information for terminator characters (PR preprocessor/77672)
substring_loc::get_location currently fails for the final terminator
character in a STRING_CST from the C frontend, so that format_warning_va
falls back to using the location of the string as a whole.
This patch tweaks things [1] so that we use the final closing quote
as the location of the terminator character, as requested in
PR preprocessor/77672.
[1] specifically, cpp_interpret_string_1.
