Narayan Kamath 162ea0e9e8 Remove global variables from ProcessState.
These weren't really being used and they make it
very hard to reason about who looks at command line
arguments.

Processes started via app_process (this includes all
zygote forks and the system_server) can get information
about command line arguments from the AndroidRuntime
class, which is available via a call to
AndroidRuntime::getRuntime.

bug: 13647418
