linker: Recalculate interface variables (#4784)
* linker: Recalculate interface variables

By resolving extern symbols Entry Points might access variables they
hadn't declared before.

* test/linker: add test to verify linked spir-vs importing functions validate

Without the fix Validate will complain about:

"ERROR: 9: Interface variable id <5> is used by entry point 'bar' id <1>, but is not listed as an interface\n  %5 = OpVariable %_ptr_Input_v3uint Input\n"
