Describe the Bug

The SignatureComprer class can be configured to slightly relax the strict comparisons that are made for assemblies and types. This relaxation is however not reflected in the GetHashCode implementations. This can result in two members that would be considered equal according to the relaxed rules having two different hashcodes, making it unusable for HashSet<TMember> and Dictionary<TMember, TValue>.

How To Reproduce

var comparer = new SignatureComparer(SignatureComparisonFlags.VersionAgnostic);

var reference1 = KnownCorLibs.SystemRuntime_v5_0_0_0;
var reference2 = KnownCorLibs.SystemRuntime_v6_0_0_0;
Assert.Equal(reference1, reference2, comparer);
        
var set = new HashSet<AssemblyReference>(comparer);
Assert.True(set.Add(reference1));
Assert.False(set.Add(reference2));

Expected Behavior

All checks pass.

Actual Behavior

The last Assert.False fails.
