Create CarSystemUIEvsRRO

This CL creates CarSystemUIEvsRRO that allows to change the EVS camera
preview activity in runtime.  By default, this CL configures it to use
CarEvsCameraPreviewActivity.

Also, this CL introduces a new ENABLE_CAREVSSERVICE_SAMPLE build
variable.  When this variable is set as true, CarSystemUIEvsRRO and
CarEvsCameraPreviewActivity will be built.

Bug: 187832506
Test: Request to launch the preview activity with below command:
      > adb shell cmd car_service inject-vhal-event 0x11410f10 0,1

Native (C++) code format is required to be compatible with .clang-format file. Run

git clang-format --style=file --extension='h,cpp,cc' HEAD~

Note that clang-format is not desirable for Android java files. Therefore the command line above is limited to specific extensions.
