This changes the behavior of SetBreakpointForScript to find more accurate break positions. Previously, setting a breakpoint would only consider the shared function info that contained the requested position for setting a breakpoint. More intuitively, a breakpoint should not necessarily be set in a function that contains the position, but in the closest breakable location that comes after the position we requested. To achieve this we: 1. find the shared function info of the inner most function that contains the requested_position. This function's end position is used to find other shared function infos in step 2. 2. search for all shared function infos that intersect with the range [requested_position, inner_most_function.break_position[. 3. From the shared function infos extracted in 2, find the one that has the closest breakable location to requested_position.
