init.insmod.cfg: split out init.insmod.charger.rc

Create charger_insmod_sh service.  Copy a minimal set of operations
for charger into init.insmod.charger.rc, most notably do not start
adsp and cdsp as they contribute to a power drain.

Bug: 159424228
Test: confirm charger does not start adsp/cdsp
