Created the viewer component for SF traces, including rects view,
properties view, hierarchy view (for re-use in other apps). This CL
contains properties view and changes to associated reusable components.
Currently follows same design as go/winscope-beta.
Bug: b/238089034 b/232081297
Test: npm run test:all. upload/run any SF trace to see what it looks
like.
