This changes file descriptors from uint32 to int32 and the
corresponding file table to reject negative values. This ensures
invalid values aren't mistaken for very large descriptor entries, which
can use a lot of memory as the table implementation isn't designed to
be sparse.

A prior change broke race tests as it lazy set HostFunc.Name even when
saved as a field. This sets name in all places we instantiate HostFunc
for use in fields.

This makes host functions index consistently on insertion order, rather
than lexicographic order. This helps with ABI such as Emscripten, which
need an expected order.
This also constrains the internal code around host functions to only one
export name. More than one was never used. By restricting this, logic is
simpler and smaller.

`GOARCH=wasm GOOS=js` defines parameter names in go source, and they are
indirectly related to the wasm parameter "sp". This creates a pseudo
name section so that we can access the parameter names. The alternative
would be adding a hack to normal FunctionDefinition, only used for gojs.

This refactors GOOS and GOARCH specific code into their own packages.
This allows logging interceptors to be built without cyclic package
dependencies.
