dynamic_sensor: Add sensor manager init to sub-HAL 2.1.

Bug: 195964858
Test: Verified dynamic sensor manager is present in sensor list and that
 no SELinux violations occur on sc-v2-dev and master.

$ make -j28 && \
         vendor/google/tools/flashall -w -s 14281FDEE000A5 --disable_verity && \
         sleep 90 && adb root
.
.
.
$ adb shell sensor_test list | grep "sensor_test\|Type\|Dynamic"
sensor_test version 74
Type     Subtype  Name
32       0        Dynamic Sensor Manager
$ adb logcat -d | grep avc | grep sensor
$
