Auto merge of #100073 - dpaoliello:externvar, r=michaelwoerister
Add test for raw-dylib with an external variable All existing tests of link kind `raw-dylib` only validate the ability to link against functions, but it is also possible to link against variables. This adds tests for linking against a variable using `raw-dylib` both by-name and by-ordinal.
