Improved adapter selection in CTS testing

The CTS tests now have an additional --backend option, and the --platform option allows specifying platforms per-device. In addition, new targets have been added that test the "loader"; that is, where the adapter isn't forced.

+CTS Environment Variables
+-------------------------
+
+The following environment variables are used by the CTS runner and can be used to specify the platform that the test
+framework should run on. This can be used during development and testing to run an individual test under `bin/test-*`,
+or a platform for a specific backend can be chosen. If both filters are specified, then the both must match. Command
+line arguments for the test binaries take priority over these variables.
+
+.. envvar:: UR_CTS_ADAPTER_PLATFORM
+
+    A specifier list in the form of `[(backend):](platform name)[;[(backend)]:(platform name)]...`. For example:
+    `Fictional Corp(R);LEVEL_ZERO:Another Fictional Corp(R)`. If a backend specific specifier is present in the list and
+    the test is running for that backend, the device with the given name is chosen. Otherwise, it must match the name of
+    the specifier with no backend in the list.
+
+.. envvar:: UR_CTS_BACKEND
+
+    A backend to force the test to use. For example, `OPENCL`, `LEVEL_ZERO`, `HIP` and so on.
