meta-agl-profile-core: remove agl-service-steering-wheel

Nothing in-tree uses the agl-service-steering-wheel binding, which
was specific to one particular older demo setup with a USB steering
wheel peripheral.  As well, it has never been converted to use the
CMake app templates, and thus lacks proper support for building
debug/test/coverage widgets.  To ease maintenance effort and keep
the core set of APIs cleaner, remove it.
