feat: collect test location

[claneo]

Summary

1. Collect test location via error stack
2. list command
   1. Added new option --printLocation
   2. List test suites too
3. Added new reporter hook onTestFileReady, this will be used in vscode extension later

The location maybe inaccurate because rspack transpiled describe() call to (0,rstest_core.describe)(), so the location got from error stack is the end of the comma expression. Chained method is not affected expect describe.for which is tranpiled to describe["for"].

$ cd e2e && npx rstest list ./build --printLocation
