This commit adds makefiles that allow libcamera to build inline with AOSP, with one example of how to do so documented in [0]. Note that meson_cross.mk is adapted from the Mesa project [1]. As Android support matures, it will be useful to document how to integrate libcamera for distribution owners [Bug].
