[platforms/hwcomposer] Few fixes for hwcomposer platforms

Browse source 
Summary:
- Actually use double layered compositing, previously both layers were
of type HWC_FRAMEBUFFER, instead of 2nd layer being
HWC_FRAMEBUFFER_TARGET. Thanks to @NotKit on telegram for pointing this
out.

- Use sourceCropf instead of sourceCrop, as sourceCrop is legacy option.

Test Plan: have to test on actual device, but test_hwcomposer does have similar code.
