Some system services (e.g. SoundTriggerMiddleware) assume that
whenever they start, the audio HAL is in its default (reset) state.
init.rc scripts tie the lifetimes of the audio HAL and system
processes, but when using stop/start this is not the case, and this
may cause spurious crashes in this case.
stop/start is apparently being relied on in some test infrastructure,
so this change is needed to avoid causing problems for those systems
or false detection of problems, which are not actually present in
production.
Bug: 154029444
Test: Manually verify that the audio HAL is stopped on
'adb shell stop', restarted on 'adb shell start' and that the
system boots correctly after.

iorapd depends on pm in system_server, so turn it off too when we
turn off system_server with the 'stop' command.

Move these from toybox as they're Android specific and more easily
maintained here.
A few changes during the conversion:
* Report error in setprop if value is not a UTF8 string; this would
previously fail only after attempting to set the property
* Inform users to check dmesg for further failure messages for all
three programs
* Only start/stop zygote_secondary if the device is not single arch
Bug: 117321744
Bug: 133901248
Test: setprop works, start and stop work on single and multi-arch.
