Add function signatures to metadata

[mattjohnsonpint]

This PR is dependent on AssemblyScript/assemblyscript#2832, released with AssemblyScript 0.27.26.

Completes HYP-851

Note, the embedded metadata format has changed. It used to be split up in several wasm custom sections. It's now in one custom section named hypermode_meta, encoded as JSON. This will allow us to add more metadata in the future with minimal impact. This change, however, is incompatible with the current runtime. We'll need a corresponding change there as well.

There's also a lot of refactoring, including making the transform a TypeScript project of its own.

Also, we now emit metadata during the build, including a color ascii art logo (which we can update if desired). Example:

HYP-851 Extract function signatures

We'll need to be able to "read" the user's functions so we can map them to GraphQL.

In a compiler transform:

1. Examine the module's exported functions
2. Reconstruct the function signature:
   • Function name
   • Parameter names and types
   • Return type
3. Gather type definitions used in the signature, recurse to include all referenced types
4. Export function signatures and types to wasm metadata. (format TBD)

The runtime will use the metadata to generate corresponding GraphQL Schema.

I also updated some of the CI workflows, and added a new one that builds the example projects. You can see the hypermode build output in the logs here:
