And also make sure that even long names don't get truncated.

The WebAssembly specification requires the "name" property of (exported)
function wrappers to hold the index of the function within the module,
and the default ToString algorithm for Function instances thus generates
something along the lines of `function 42() { [native code] }`, which is
technically correct, but not very useful to developers to diagnose
(humans don't think of functions in a module in terms of their indices).
With this CL, we change the description returned for Wasm (exported)
functions to use the debug name of the Wasm function instead.

This changes the names reported in stack traces via the Chrome DevTools
protocol to follow the WAT naming convention for functions. This aligns
the behavior here with the rest of DevTools (i.e. the disassembly in the
Sources panel and the Scope sidebar, as well as the Console REPL) to use
one consistent naming scheme.

As per WebAssembly Web API[1], the engine should only consider names
from the name section to synthesize function names in the context of
call stacks. We previously also added support to harvest the exports
table here in an attempt to improve the DevTools debugging experience,
but that needs a separate fix specifically for the inspector (which
should also take into account the imports to harvest names).

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/987a7f4ae45ebfc986525075277debdf73001fc2 because
types are more complicated now.
