Reorganized rootcomponentgenerator package and added demo.

-Moved rootcomponentgenerator/annotations to dialer/inject to reduce the number of deps engineers need to include

-Move rootcomponentgenerator/processor into rootcomponentgenerator/ since the other package is now gone

-Added inject/demo and tests

TEST=unit, tap
Test: unit, tap
