Improve testing of AdviceMap in Mast

[paracetamolo]

What should be done?

The vendoring PR #1643 should test that the adviceMap of a vendored library is copied to assembled library.
It's not easy to create MAST Forest that contains AdviceMaps using the assembler.

How should it be done?

We should check with the compiler the best way to use the adviceMap.

When is this task done?

We should provide an API to populate the adviceMap, in accordance with how the compiler uses it, and complete the vendoring test.
