Android car service配置
配置路径：
- config_occupant_zones
主要是配置车上的每个zone对应的是什么角色(occupantType)，这个zone在车上的位置(seatRow + seatSide共同决定)
下面是配置项说明：
<!--
Lists all occupant (= driver + passenger) zones available in the car.
Some examples are:
<item>occupantZoneId=0,occupantType=DRIVER,seatRow=1,seatSide=driver</item>
<item>occupantZoneId=1,occupantType=FRONT_PASSENGER,seatRow=1,seatSide=oppositeDriver</item>
<item>occupantZoneId=2,occupantType=REAR_PASSENGER,seatRow=2,seatSide=left</item>
<item>occupantZoneId=3,occupantType=REAR_PASSENGER,seatRow=2,seatSide=right</item>
occupantZoneId:
含义：全局唯一的ID （Unique unsigned integer id to represent each passenger zone. Each zone
should have different id.）
occupantType:
含义：乘客类型 （Occupant type for the display. Use * part from
CarOccupantZoneManager.OCCUPANT_TYPE_* like DRIVER, FRONT_PASSENGER,
REAR_PASSENGER and etc.）
seatRow: 乘客在那一排 （Integer telling which row the seat is located. Row 1 is for front seats.）
seatSide: 乘客在那边的座位 （left/center/right for known side. Or can use driver/center/oppositeDriver to
handle both right-hand driving and left-hand driving in one place.
If car's RHD / LHD is not specified, LHD will be assumed and driver side becomes
left.）
-->
<string-arraytranslatable="false"name="config_occupant_zones">
<item>occupantZoneId=0,occupantType=DRIVER,seatRow=1,seatSide=driver</item>
</string-array>
- config_occupant_display_mapping
定义物理屏幕（displayPort）的作用（displayType），以及属于哪个Zone（occupantZoneId），Zoneid必须和
config_occupant_zones中的id相匹配。
displayType的取值和作用参考CarOccupantZoneManager代码中的注释。
<!--
Specifies configuration of displays in system telling its usage / type and assigned
occupant. DEFAULT_DISPLAY, if assigned here, should be always assigned to the DRIVER zone.
Some examples are:
<item>displayPort=0,displayType=MAIN,occupantZoneId=0</item>
<item>displayPort=1,displayType=INSTRUMENT_CLUSTER,occupantZoneId=0</item>
<item>displayPort=2,displayType=MAIN,occupantZoneId=1</item>
<item>displayPort=3,displayType=MAIN,occupantZoneId=2</item>
<item>displayUniqueId=virtual:com.example:MainD,displayType=MAIN,occupantZoneId=3</item>
NOTE: each item should have displayPort or displayUniqueId, if it has both, displayPort
will be used.
displayPort: Unique Port id for the physical display.
displayUniqueId: Unique Id for the display.
The unique id of the virtual display will be the form of 'virtual:<PACKAGE>:<ID>'.
displayType: Display type for the display. Use * part from
CarOccupantZoneManager.DISPLAY_TYPE_* like MAIN, INSTRUMENT_CLUSTER and
etc.
occupantZoneId: occupantZoneId specified from config_occupant_zones.
