Reduce use of "exported_system_prop" by defining 2 new (currently
identical) "locale_prop" and "timezone_prop" types for the system
properties that are for "global system settings". See the comments in
private/property_contexts for details.
Initially the rights of the new types should be identical to
exported_system_prop but they will be reduced with a follow-up commit to
enable easier rollback / progress to be made on related work.

ro.log.file_logger.path is a system property that liblog uses to
determine if file_logger should be used (instead of logd) and what file
the logs should be emitted to. It is primarily meant for non-Android
environment like Microdroid, and doesn't need to be set in Android. In
fact, setting it to a wrong value can break the system logging
functionality. This change prevents such a problem by assigning a
dedicated property context (log_file_logger_prop) to the property and
making it non-writable. (Note that it still has to be readable because
liblog reads it and liblog can be loaded in any process)

Previously in Microdroid, processes send log messages to logd over
socket and then logcat ran to hand the message to the host side over the
serial console.
That has changed. Now, the liblog library which processes use to emit
logs directly sends the given message to the serial console. Liblog does
this by reading a new system property ro.log.file_logger.path. When this
is set, liblog doesn't use the logd logger, but opens the file that the
sysprop refers to and writes logs there.
This change implments sepolicy side of the story.
* logd and logcat types are removed since they no longer are needed.
* existing references to those types are removed as well.
* a new property type `log_prop` is introduced and the two system
properties are labaled as log_prop
* all processes have read access to the system properties
* all processes have append access to /dev/hvc2

Test: run microdroid, see log is still emitted.

New ro.kernel.watermark_scale_factor property is used to store the
original value read from /proc/sys/vm/watermark_scale_factor before
extra_free_kbytes.sh changes it. The original value is necessary to
use the same reference point in case the script is invoked multiple
times. The property is set by init the first time script is invoked
and should never be changed afterwards.

Next attempt at rolling forward aosp/2200430. It appears the
first-stage-init did not create the /dev/selinux folder on GSI
instances, resulting in breakages when selinux.cpp tries to copy files
to that folder.
