feat(cli/source_map): Use top user frame for error source lines (#9604)
This commit changes formatting of JS errors; by not showing 
source lines for internal code. Where possible, instead using 
the top stack frame associated with user code i.e. the first 
location that is colourful and not a "deno:" URL.
