include: android: Add Android headers from Cros
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/ Signed-off-by: Jacopo Mondi <jacopo@jmondi.org> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
