android: Update Android headers

Browse source 
Import the latest version of the Android headers from Chrome OS (commit
a30340e77ec8 ("camera: Uprev Android camera headers")). This brings in
the Camera HAL v3.5 support.

The headers are imported verbatim, except for the addition of the SPDX
headers.

* - Addition of camera3 stream configuration operation mode to camera3_stream_configuration_t
*
* 3.4: Minor additions to supported metadata and changes to data_space support
*
* - Add ANDROID_SENSOR_OPAQUE_RAW_SIZE static metadata as mandatory if
* RAW_OPAQUE format is supported.
*
* - Add ANDROID_CONTROL_POST_RAW_SENSITIVITY_BOOST_RANGE static metadata as
* mandatory if any RAW format is supported
*
* - Switch camera3_stream_t data_space field to a more flexible definition,
* using the version 0 definition of dataspace encoding.
*
* - General metadata additions which are available to use for HALv3.2 or
* newer:
* - ANDROID_INFO_SUPPORTED_HARDWARE_LEVEL_3
* - ANDROID_CONTROL_POST_RAW_SENSITIVITY_BOOST
* - ANDROID_CONTROL_POST_RAW_SENSITIVITY_BOOST_RANGE
* - ANDROID_SENSOR_DYNAMIC_BLACK_LEVEL
* - ANDROID_SENSOR_DYNAMIC_WHITE_LEVEL
* - ANDROID_SENSOR_OPAQUE_RAW_SIZE
* - ANDROID_SENSOR_OPTICAL_BLACK_REGIONS
*
* 3.5: Minor revisions to support session parameters and logical multi camera:
*
* - Add ANDROID_REQUEST_AVAILABLE_SESSION_KEYS static metadata, which is
* optional for implementations that want to support session parameters. If support is
* needed, then Hal should populate the list with all available capture request keys
* that can cause severe processing delays when modified by client. Typical examples
* include parameters that require time-consuming HW re-configuration or internal camera
* pipeline update.
*
* - Add a session parameter field to camera3_stream_configuration which can be populated
* by clients with initial values for the keys found in ANDROID_REQUEST_AVAILABLE_SESSION_KEYS.
*
* - Metadata additions for logical multi camera capability:
* - ANDROID_REQUEST_AVAILABLE_CAPABILITIES_LOGICAL_MULTI_CAMERA
* - ANDROID_LOGICAL_MULTI_CAMERA_PHYSICAL_IDS
* - ANDROID_LOGICAL_MULTI_CAMERA_SYNC_TYPE
*
* - Add physical camera id field in camera3_stream, so that for a logical
* multi camera, the application has the option to specify which physical camera
* a particular stream is configured on.
*
* - Add physical camera id and settings field in camera3_capture_request, so that
* for a logical multi camera, the application has the option to specify individual
* settings for a particular physical device.
