libgui: Add native window attributes to query usage

This is required to enable GL libraries to query usage
native window attributes to enable/disable tile rendering.

Change-Id: If752fa26ac3d8ffd7776cc5a16fe162af0742df5
sensorservice: Add legacy sensors fusion.

This change allows devices with accelerometer & magnetometer but
without gyroscope to still get virtual sensors such as Gravity,
Linear Acceleration, Orientation & Rotation Vector.

Can be disabled with BOARD_USE_LEGACY_SENSORS_FUSION := false
