Have some shell start activity commands go thorugh AMS instead of ATMS (28/n)

Some shell start activity commands set debug flags that requires us
to synchronously call into the process logic in AMS in the middle of starting
an acitivty in ATMS. To avoid dealock in this situation, we have the shell
commands go throuhg AMS to start activity which will in turn acquire the AMS
lock before calling into ATMS.
