This adds support for WasmGC objects (structs/arrays) to the
inspector backend. For prettier printing, it also adds support
for reading the "type" and "field" subsections of the "name"
section in Wasm modules.

This patch includes a revert of most of commit
crrev.com/987a7f4a because
types are more complicated now.
