On a very parallel debug build, I see a long time just waiting for
bindgen / style compilation / geckoservo.
Turns out that a bunch of this is just proc macros / build scripts.
Optimizing it saves between 10 and 17 seconds of my debug build. We
might want to consider running bindgen much like cbindgen rather than
rebuilding it all the time, which should help a lot more, but my guess
is that this should still help with the pretty hot custom derives that
the style crate runs.
This needs rust 1.41, so the requirement for tools/crashreporter needs
to be bumped as a consequence. To make things simpler, it was bumped
to 1.47 while we're at it.

This updates the relevant CL and wasmparser versions:
* wasmparser 0.67
* Cranelift/wasmtime to dcc52ba3f69d3de7cdbd787b936825d9c61e3c27
on branch firefox85 at https://github.com/mozilla-spidermonkey/wasmtime
It also includes the following changes needed to track CL/wasmparser ABI changes:
* test suite: track improvements to validation-failure expected outputs.
* wasm/cranelift/src/bindings/mod.rs, ModuleEnvironment::signature: track
CL-side changes towards module-linking support.
* wasm/cranelift/src/wasm2clif.rs: FuncEnvironment::translate_memory_copy:
track CL-side changes for supporting multiple memories.

This PR updates wgpu to the latest and changes the way we pass object descriptors to the GPU process.
Instead of trying to convert them between DOM-CPP-IPDL-FFI-Rust, we now do DOM-FFI-Rust
and serialize them by serde into ipc::ByteBuf objects.

This patch pulls in an updated Cranelift with a new validation strategy,
introduced by bytecodealliance/wasmtime#2059. This new design validates
the Wasm module as it parses the function bodies. A subsequent patch
will adapt Baldrdash to work with this.

We need this bump for a couple of reasons:
1. It enables floating the libc crate version, which makes keeping up-to-date
with upstream changes easier.
2. It enables floating the getrandom crate version, which enables updating
getrandom to a version with less buggy behavior around the Linux
`getrandom` syscall on some architectures.
We also take this opportunity to sync up our vendored lucet with the lucet
that we use to build things in taskcluster.

This lays out a Rust crate and statically links it into
`windows-default-agent.exe`. It declares a single-method API (which
will be invoked in the next commit).
Strings cross the C/C++ <-> Rust FFI boundary as null-terminated
UTF-8. (This will matter more if and when we use ETag and
If-None-Match to get 304 results.)
Errors are reported as Windows result codes, with the "customer" bit
set to encode certain classes of failure.
The bulk of the work is in implementing a
[Viaduct](https://github.com/mozilla/application-services/tree/master/components/viaduct)
backend built on top of `wininet.dll`. The motivation is that if and
when this Remote Settings Rust client grows features (say,
Content-Signature: verification), then by using Viaduct there is a
smooth path to consume the client inside Firefox itself, because
Viaduct already has a backend on top of Necko. That makes this
abstraction relatively low friction: it exists, is in-tree already,
and has a path to use in Gecko proper.
It is expected that the layer above this will handle "gracefully
failing", either open or closed; and will mirror Remote Settings
configuration to the registry so that testers can use prod/stage/dev
easily.
For follow-up:
- Configure logging to use the Windows event logger. See [Bug
1648617](https://bugzilla.mozilla.org/show_bug.cgi?id=1648617).
- Consider propagating errors into the Telemetry we send.

- It includes the Spectre mitigation for explicit heap bounds checks
merged in PR bytecodealliance/wasmtime#1930, resolving Bug 1648885.

amounts merged in PR bytecodealliance/wasmtime#1954, resolving Bug
1649432.
We need to temporarily disable the `wasm/limits.js` jit-test on
Cranelift configurations because it now needs shared memory to work, and
the Cranelift backend does not support this yet. Given that this should
be ready in the next month at most (requires atomics support on AArch64,
which is currently being examined), it seems simpler to temporarily
disable the test on aarch64 than to try to disentangle the bits that
depend on shared memories explicitly.
This patch also edits the `regexp/bug1445907.js` jit-test to run only if
Wasm debugging is supported. This is needed for the test not to fail
with `--wasm-compiler=cranelift` (which disables Baseline, the only Wasm
compiler that supports debugging).
