When building with lazy initialization of the root conformance, we need to ensure that we are invoking the accessor to initialize the conformance record. We would previously generate a direct reference to the conformance, which was uninitialized, resulting in a crash at runtime. The non-windows test changes here are to use/imply static linking for the support modules. This should have no difference on the non-Windows targets, but makes a difference on Windows where this implies that everything will be built into a single module, which permits the non-indirect access to types. Unfortunately, this does somewhat regress the test coverage on Windows as we do not exercise as much of the shared linkage paths which do change some of the code-generation to deal with the moral equivalent of the GOT - the IAT. Special thanks to @slavapestov for the pointer to `isDependentConformance`. This should eliminate the last known issue with cross-module protocol conformances. Fixes: SR-14807
