feat(amino): Add TypeDesc Amino implementation and TypedValue marshaler

[gfanton]

PS: This PR is still in draft, but I would welcome any feedback on it

This PR has two main objectives. The first is to add a TypeDesc method implementation to Amino, allowing a type to self-describe. The second is to introduce a new package, gnoamino, dedicated to (un)marshaling Gno types, starting with gnolang.TypedValue and its TypedValueWrapper, which implements the TypeDesc Amino method.

Most of the methods in TypedValueWrapper are inspired by or copied from gnonative.go. They are exported here for several reasons:

1. The methods in gnonative are intended for general use and may be removed later, while the ones here are focused solely on marshaling and unmarshaling.
2. These methods can be simpler, as they do not require the full support of reflection, enabling a more detailed implementation.
3. We assume prior knowledge of the type of the TypedValue, simplifying its management.
4. We will likely implement gas consumption calculations within those methods.
