Bug 1836723 - Link against ntdll for rustc 1.70. r=firefox-build-system-reviewers,ahochheiden, a=dmeehan

Building with rustc 1.70 adds a dependency to the ntdll library through
libstd using NtCreateFile/NtWriteFile (it previously picked the symbols
at runtime).

# ignore-this-changeset

When delazifying inner module functions on-demand, the JSObject global is
defined as the enclosing scope. This scope is set by the
`CompilationStencil::instantiateStencilAfterPreparation`, as it is shared
between all instantiated modules.

The problem is that the Global scope is not explicit in the Stencil. Thus, when
doing a concurrent delazification from a Stencil, the global scope is not listed
as the enclosing scope of the module.

This patch, hacks the InputScope to work-around the lack of enclosing scope of
Modules, to artificially add a fake-GlobalScope, which is later used by other
functions, such as `ScopeContext::seachInEnclosingScope` to resolve named values
such as `undefined`.

Bug 1638045 - Allow parallel jit-tests to run up to 8-way on Windows r=spidermonkey-reviewers,jonco,mgaudet

Differential Revision: https://phabricator.services.mozilla.com/D179702

This patch allows the use of a JS shell binary, compiled to
`wasm32-wasi` (WASI ABI on WebAssembly), to make use of the Wizer
snapshotting tool to embed JavaScript source with SpiderMonkey to run in
a standalone Wasm module.

If enabled with `--enable-js-shell-wizer`, the shell no longer provides
an interactive REPL; instead, when invoked during the "initialization"
phase of Wizer, it reads JS source on standard input, then
saves JS state (the global, the context, etc) for later. When the
execution is snapshotted and the snapshot is later executed as an
ordinary WASI command, the resume entry-point invokes a JS function
named `main` in the global scope, if any.

An example of how to use this follows:

```
$ echo "function main() { print('hello world'); }" | \
  wizer --allow-wasi -r _start=wizer.resume obj-release/dist/bin/js \
  -o snapshotted.wasm

$ wasmtime snapshotted.wasm
hello world
$
```

Renames InitialHeap because it's not just used for the initial heap now. Also
makes it into an enum class.
