Add missing issues.targets from #36253 (#36351)

* Add missing issues.targets from #36253

PR #36253 enabled building all tests on OSX. It was intended to include this list of
tests to disable on unsupported platforms. This was dropped as part of rebasing for
dev/infra branch.

Lack of CI on dev/infra allowed this to be missed.

* Revise issues.targets

* Add src/coreclr/tests/src/baseservices/typeequivalence/simple

* Remove #if Windows from DllImportPathTest
