[tools][devshell][aemu] Add gRPC flag
DX-1617 #comment
This provides a mechanims to control and stream the output
of the emulator to a remote host, which is useful for remote
workflows.
This also adds the -no-window flag when running in headless
mode, which is needed by the webrtc bridge to work in the
headless setup.
Test: fx aemu -g 5556
