android_system_sepolicy/public/property_contexts
Steven Moreland d47b09f1d9 Add context for ro.boot.product.hardware.sku.
This was defined, but it had no users in the Android tree.
Because of this, ODM manifests required extra sepolicy to be applied
in vendor. Before this, there was no policy split, so that was okay,
but now it is impossible.

Bug: 91735839
Test: add an odm manifest for SE conditional on
    a system property (ro.boot.product.hardware.sku)
    and make sure it is read into the manifest (using
    the vintf tool) and also that a client can get the
