I added ro.bionic.(2nd_)?_(arch|cpu_variant) to vendor system
properties. And have init to write them to files under dev/.
This change set SELinux rules for these properties and files.
For the system properties: vendor/default.prop will set them. init will
read them.
For the files /dev/cpu_variant:.*: init will write them. bionic libc
will read them. (Basically world readable).
This is to allow libc select the right optimized routine at runtime.
Like memcpy / strcmp etc.
Test: getprop to make sure the properties are set.
Test: ls -laZ to make sure /dev/cpu_variant:.* are correctly labeled.

device_config_flags_health_check_prop is used for enabling/disabling
program flags_health_check which is executed during device booting.
"1" means enabling health check actions in flags_health_check, other
values mean flags_health_check will not perform any action.

mtd_device does not label any /dev node present on walleye, and the only
permission to that type is:
allow hal_telephony_server mtd_device:dir search;

A sysprop apexd.status is set by apexd, to that other components (i.e.
init) can determine whether APEXs are all successfully mounted or no
(i.e., being mounted).
The sysprop is only writable by apexd.

Test: adb shell getprop apexd.status returns 'ready'.

New maintenance scheme for mapping files:
Say, V is the current SELinux platform version, then at any point in time we
only maintain (V->V-1) mapping. (V->V-n) map is constructed from top (V->V-n+1)
and bottom (V-n+1->V-n) without changes to previously maintained mapping files.
Caveats:
- 26.0.cil doesn't technically represent 27.0->26.0 map, but rather
current->26.0. We'll fully migrate to the scheme with future releases.
Bug: 67510052
Test: adding new public type only requires changing the latest compat map

/system/usr/share/zoneinfo is currently labeled zoneinfo_data_file,
a label shared with /data/misc/zoneinfo. However, each of these
directory locations has different security characteristics. In
particular, the files in /system/usr/share/zoneinfo must never be
writable, whereas /data/misc/zoneinfo may be written to by system_server.
Reusing the same label hides these different security characteristics.
Create a separate label for /system/usr/share/zoneinfo.
Test: Device boots and no obvious problems.
