Report no DisplayDecorationSupport in GL
Previously we were using an EGLConfig that is out of line with the spec
in order to support this. It would be more work to get this to work
properly, and the devices we're shipping with hardware support will
always be using Vulkan in HWUI. Simply disable the feature, so that
such a device can still work when switched to use GL.
Add a new APEX header for querying various system properties. This matches
how libandroid_runtime accesses other HWUI utilities. Currently the new
header only includes one method, but could be expanded in the future to
include other properties.
