Updated Winscope view for IME tracing InputMethodManagerService information

Updated the IME tracing view in Winscope for the new optimized proto
dump format. This change adds the IMMS view separately from the
previously added clients and IMS views.

Bug: 154348613
Test: build and run the code using "yarn run dev"
      build and flash the android code to a device
      start and stop IME trace from the command line and then upload the files into Winscope or
      start IME trace from the web interface, open an IME on the android device to generate logs, end trace from the web interface to see the logs
