* Introduce --interface-api={c,packed} parameter
This introduces structures generated to provide a documented and stable user
friendly interface to a TVM generated model, as can be seen in the AOT
demo application:
```
struct tvmgen_default_inputs inputs = {
.input_1 = input_data,
};
struct tvmgen_default_outputs outputs = {
.output = output_data,
};
int ret_val = tvmgen_default_run(&inputs, &outputs, NULL, NULL);
```
To facilitate this, some other changes are included:
* Removed dependency on `aot_executor.{c,h}` in tests, pending the
discussion in the interface RFC as to whether we keep them.
* Moved creation of test DLTensor's into the AOT test utils, in future this
can be replaced by loading via the Python API or otherwise
* Introduce `parametrize_aot_options` which can be used to test
permutations of AOT which work together - for now this filters C
interface and packed operators
* Updated demo application to generate the header for demonstration
purposes, we should consider porting the demo application to Model
Library Format and using the toolchain in the Zephyr App via CMake
instead?
This patch builds upon the improvements @giuseros made to AOT testing
and name mangling from #8014
* Tweak metadata variable description and MLF target loop
* Remove direct usage of `relay::Var` in meta_data.h
This looks like the only place that could be causing the Windows CI failures, so trying removing the additional header in meta_data.h
* Linting fix
* Post-rebase files fixing
These tests were somehow transmuted in transit, I've updated them to the
most recent variant of the test helpers.
* Strip back interface API to just inputs and outputs
This removes any speculative structures from the generated code and cleans up some of the documentation.
* Add header guards and tweak documentation
