By adding builder style usage to most of the layer interface, it is easier to
create and use layers in tests. This commit refactors the layer interface and
updates most of the tests to use this style.
Made InstanceWrapper and DeviceWrapper simpler to use by moving them to test_environment
then making the Create() member functions and doing the gtest assertions in the function
itself.
Additionally:
Removed the `detail` namespace in the test_environment.
Renamed get_new_test_icd/layer to just `reset_icd/layer`. This is clearer about what it
is doing and makes the interface more expressive with code such as
`env->reset_icd().SetMinInterfaceVersion(5);`
* `get_instance_func` needed to have __stdcall (VKAPI_ATTR) added
* Several .def files were incorrect
* vk_layer.h forward declares vkNegotiateLoaderLayerInterfaceVersion. This is
problomatic because it doesn't have __declspec(dllexport), a token added by
FRAMEWORK_EXPORT on windows. We have to special case the export macro here to
prevent that mismatched definition.
Functions needed in the various layer interface versions are now
exported as well as guarded behind macros configurable from CMake.
The export_definitions folder was populated as well.
