include: android: Add Android headers from Cros

Browse source 
Copy the Android Camera3 HAL headers from the ChromiumOS build system
and define a new inclusion directive in the meson build system for them.

The header files have been copied from:
https://chromium.googlesource.com/chromiumos/platform2
at revision 9e65ddd2c496e712f005ada9715decd2ff8e4a03
and provide:

1) Android CameraHAL3 HAL headers in include/android/hardware/
2) The Android system headers in include/android/system/
3) The Android camera metadata headers in include/android/metadata/

The original path in the Cros platform2/ repository is, respectively:
camera/android/header_files/include/hardware
camera/android/header_files/include/system
camera/android/libcamera_metadata/include/

* platform release 1.5
*
* Third-party source AND binary code relies on the definitions
* here to be FROZEN ON ALL UPCOMING PLATFORM RELEASES.
*
* - DO NOT MODIFY ENUMS (EXCEPT IF YOU ADD NEW 32-BIT VALUES)

/*
* Support routines to send messages to the Android in-kernel log buffer,
* which can later be accessed through the 'logcat' utility.
*
* Each log message must have
* - a priority
* - a log tag
* - some text
*
* The tag normally corresponds to the component that emits the log message,
* and should be reasonably small.
*
* Log message text may be truncated to less than an implementation-specific
* limit (e.g. 1023 characters max).
*
* Note that a newline character ("\n") will be appended automatically to your
* log message, if not already there. It is not possible to send several messages
* and have them appear on a single line in logcat.
*
* PLEASE USE LOGS WITH MODERATION:
*
* - Sending log messages eats CPU and slow down your application and the
* system.
*
* - The circular log buffer is pretty small (<64KB), sending many messages
* might push off other important log messages from the rest of the system.
*
* - In release builds, only send log messages to account for exceptional
* conditions.
*
* NOTE: These functions MUST be implemented by /system/lib/liblog.so

* corrupted by subsequent preview frames filled by the camera. This flag is
* recommended only when copying out data brings significant performance price
* and the handling/processing of the received frame data is always faster than
* the preview frame rate so that data corruption won't occur.

* For instance,
* 1. 0x00 disables the callback. In this case, copy out and one shot bits
* are ignored.
* 2. 0x01 enables a callback without copying out the received frames. A
* typical use case is the Camcorder application to avoid making costly

* 3. 0x05 is enabling a callback with frame copied out repeatedly. A typical

* in the composer is identity. This can be very useful when used in
* conjunction with the h/w composer HAL, in situations where it
* cannot handle arbitrary rotations.
*
* 1. Before dequeuing a buffer, the GL driver (or any other ANW client)
* queries the ANW for NATIVE_WINDOW_TRANSFORM_HINT.
*
* 2. The GL driver overrides the width and height of the ANW to
* account for NATIVE_WINDOW_TRANSFORM_HINT. This is done by querying
* NATIVE_WINDOW_DEFAULT_{WIDTH | HEIGHT}, swapping the dimensions
* according to NATIVE_WINDOW_TRANSFORM_HINT and calling
* native_window_set_buffers_dimensions().
*
* 3. The GL driver dequeues a buffer of the new pre-rotated size.
*
* 4. The GL driver renders to the buffer such that the image is
* already transformed, that is applying NATIVE_WINDOW_TRANSFORM_HINT
* to the rendering.
*
* 5. The GL driver calls native_window_set_transform to apply
* inverse transformation to the buffer it just rendered.
* In order to do this, the GL driver needs
* to calculate the inverse of NATIVE_WINDOW_TRANSFORM_HINT, this is
* done easily:
*
* int hintTransform, inverseTransform;
* query(..., NATIVE_WINDOW_TRANSFORM_HINT, &hintTransform);
* inverseTransform = hintTransform;
* if (hintTransform & HAL_TRANSFORM_ROT_90)
* inverseTransform ^= HAL_TRANSFORM_ROT_180;
*
*

* transform. If the buffer transform happens to cancel out the
