1a2d8e48 - Promote feature NonescapableAccessorOnTrivial to be non-experimental

The flag only exists so we can introduce a new API: UnsafeMutablePointer.mutableSpan. Supported compilers cannot handle the new API. rdar://154247502 (Promote feature NonescapableAccessorOnTrivial to be non-experimental)
