sm8750-common: Update target level to 202404

The target level as per requirements is 202404. This change is to set
the manifest target level to the same.

As the per the requirement, HIDL interfaces should not be used, hence
this change is removing the hwservicemanager bootup and its signal to
wait until its ready.
