Make frame address meaningful without debuginfo

The current address obtained through Frame::ip is meaningless in production environment without debuginfo. The lack of a base address prevents us from resolve symbol afterwards.

We have two solutions to this problem.

1. Expose backtrace::symbolize::native_libraries, which will allow users to record all loaded libs, and users can get bais from them. but this may reveal too many details.
2. Add a backtrace::resolve2 or make backtrace::resolve return the correct svma and library name even without debuginfo.

Start by reading the current behavior of Frame::ip and backtrace::resolve, then compare it with the proposed symbolize::native_libraries API. Determine whether the change should expose loaded-library bases or make resolve return an SVMA and library name without debuginfo. Done means one agreed API behavior is implemented and verified for production addresses without debuginfo.
