Assembly resolver static instance makes the assembly resolving wrong in multiple projects scenario

Short summary (3-5 sentences) describing the issue.

Assemblies affected

Which assemblies and versions are known to be affected e.g. OData ModelBuilder 1.x

Reproduce steps

There's a static instance for the default assembly resolver.
https://github.com/OData/ModelBuilder/blob/master/src/Microsoft.OData.ModelBuilder/Helpers/DefaultAssemblyResolver.cs#L21

In multiple projects scenario, for example there's "v1" and "v2" model builder.

"v1" reference Assembly A, B, C.
"v2" reference Assembly A, B, C, and D.

If we build the V1 first, Default assembly only loads "A, B, C".
When build "v2", since the default assembly statically in memory, it load "A, B, C", then there's no opportunity to load "D".

Expected result

What would happen if there wasn't a bug.

Actual result

What is actually happening.

Additional detail

Work around, create your own AssemblyResolver and input into the convention model builder.

Start with src/Microsoft.OData.ModelBuilder/Helpers/DefaultAssemblyResolver.cs, especially the static default resolver referenced in the issue. Reproduce the v1/v2 model-builder sequence with assemblies A, B, C, and D, then trace how the resolver is reused. Done means the second project can resolve its additional assembly without requiring a custom AssemblyResolver.
