[SILParser] fix parsing issues for stored_with_trivial_accessors.

Before this commit, we were not able to differentiate between stored
property and stored_with_trivial_accessors property. This causes issues
when parsing a SILDeclRef to a trivial getter.

We add @sil_stored for stored properties and we will have 3 cases
A) for stored property: @sil_storage var x : Int
B) for stored_with_trivial_accessors property:
   @sil_storage var x : Int { get set }
C) for computed property: var x : Int { get set }
