scp scmi-v2: Build scmi updated to use scmi-v2

build_package build_scmi_lib_scp_tools has been updated to work with
scmi-v2 as the build command has changed for this version.
The clock and sensor protocols have been excluded as they could not run
on hardware.

In addition, the branch for clone_tf_for_scp_tools is updated.
