<pre>
    At the moment, the execution test-suites correctly test that the root signature compiles correctly and that we generate the correct directx container to run the test shaders appropriately. However, there is no current tests to check that the specific values of the binary root signature are set as expected.

This issue proposes to use the `obj2yaml` tool to allow direct inspection of the root signature values.

For instance, we can set `offset = DESCRIPTOR_RANGES_OFFSET_APPEND` and we want to verify that this value is not computed to a discrete offset in the binary blob.

AC:
- [ ] Add a check-line to the root signature tests to run `obj2yaml` and verify the values of the binary are produced as expected
