There is a list of 'stable_properties' that vendor_init can use as
property triggers for Treble property compliance. This list came about
since init parses init scripts before all partitions are mounted and
therefore before all property context files are available, such that
init cannot use the normal SELinux mechanisms for determining if a
given property is vendor_init readable.
Currently though, we require all partitions that would contain
property context files to be mounted during first stage mount, so we
can use the normal SELinux mechanisms here, so this change deprecates
the stable_properties list and moves init to use SELinux to determine
if a property can be a trigger.

Test: vendor_init fails to use non-readable properties as a trigger
Test: vendor_init successfully uses readable properties as a trigger

We're moving past a world where static executables are needed,
including watchdogd, so treat this like any other executable and place
it in /system/bin.
Bug: 73660730
Test: watchdogd still runs

Allow specifying properties on the command line when running host init
verifier. This is needed particularly for importing files that have a
property expansion in their path.
Handle the import statement on host, basing paths off of the out
directory of Android builds.

This commit uses vendor sepolicy file version (defined in
`/vendor/etc/selinux/plat_sepolicy_vers.txt`) to determine whether the
source context should be set as `u:r:vendor_init:s0`.
Before this commit, the criterion was `ro.vndk.version` >= 28. However,
the check in `property_service.cpp` will always be true because
`ro.vndk.version` hasn't been loaded from `/vendor/default.prop`.
Furthermore, under some circumstances, `ro.vndk.version` may be
different from `plat_sepolicy_vers.txt` (e.g. O-MR1 vendor does not
define `ro.vndk.version`).

Currently we only report why a property set call has failed but drop
the context of what was trying to set the property. This change
adds information about why a property was trying to be set when it
fails.
It also unifies property_set() within init to go through the same
HandlePropertySet() function as normal processes do, removing unneeded
special cases.
Test: boot bullhead
Test: attempt to set invalid properties and see better error messages

Create a host side parser for init such that init rc files can be
verified for syntax correctness before being used on the device.
Bug: 36970783
Test: run the parser on init files on host
