device_config_flags_health_check_prop is used for enabling/disabling

Historically, vendor-init-actionable was created since the various
property_contexts files were not yet available when init parses its
scripts.  Since then, the property_contexts files are now always
available when init parses its scripts, so we can collapse these two
categories.

Specifically, this change ensures that all of the properties in the
previous 'stable_properties.h' file in init, which contained the
vendor-init-actionable properties, are able to be read by init
according to SEPolicy.

To ensure a surprise reboot does not take the last boot reason on
face value especially if coming from more than one boot sessions ago.
We shift and clear the value from persist.sys.boot.reason to
sys.boot.reason.last and establish a correct last reboot reason in
the canonical sys.boot.reason property.  As a result, the power
manager should read the canonical sys.boot.reason for a definitive
result rather than relying on the possibly incorrect values in the
persistent storage.  sys.boot.reason should be a core property as
it represents the canonical boot reason API.

Currently, permissions for ctl. property apply to each action verb, so
if a domain has permissions for controlling service 'foo', then it can
start, stop, and restart foo.

This change implements finer grainer permissions such that permission
can be given to strictly start a given service, but not stop or
restart it.  This new permission scheme is mandatory for the new
control functions, sigstop_on, sigstop_off, interface_start,
interface_stop, interface_restart.

This reverts commit 6f2040f8.

Reason for revert: not needed anymore after ag/3773705
This was meant to allow system_server toggling the property on/off.
Later we realized that we needed a separate property for that 
(see discussion in b/76077784) and system server happens to
have already permissions to write to sys.* properties even without
this CL.
Reverting because at this point this creates just unnecessary clutter.

To enable/disable the traced and traced_probes deamons remotely we would

See also ag/3736001.

Run:
$ adb shell 'ps -A | grep traced'

$ adb shell 'settings put global sys_traced 0'
$ adb shell 'ps -A | grep traced'
Should no longer see traced.

This CL lists all the exported platform properties in
private/exported_property_contexts.

Additionally accessing core_property_type from vendor components is
restricted.
Instead public_readable_property_type is used to allow vendor components
to read exported platform properties, and accessibility from
vendor_init is also specified explicitly.

Note that whitelisting would be applied only if
PRODUCT_COMPATIBLE_PROPERTY is set on.
