test: overhaul stack_trace testing
- limit expected-output to main source file; ie. tolerate changes to start.zig - when mode != .Debug the function name is now symbolically represented; ie. tolerate changes in llvm optimizer effects on the callstack - cleanup how test cases are specified - add test case predicates for excluding by arch, os or custom fn
