wasmtime: Overhaul trampolines (#6262)
This commit splits `VMCallerCheckedFuncRef::func_ptr` into three new function
pointers: `VMCallerCheckedFuncRef::{wasm,array,native}_call`. Each one has a
dedicated calling convention, so callers just choose the version that works for
them. This is as opposed to the previous behavior where we would chain together
many trampolines that converted between calling conventions, sometimes up to
four on the way into Wasm and four more on the way back out. See [0] for
details.
[0] https://github.com/bytecodealliance/rfcs/blob/main/accepted/tail-calls.md#a-review-of-our-existing-trampolines-calling-conventions-and-call-paths
Thanks to @bjorn3 for the initial idea of having multiple function pointers for
different calling conventions.
This is generally a nice ~5-10% speed up to our call benchmarks across the
board: both Wasm-to-host and host-to-Wasm. The one exception is typed calls from
Wasm to the host, which have a minor regression. We hypothesize that this is
because the old hand-written assembly trampolines did not maintain a call frame
and do a tail call, but the new Cranelift-generated trampolines do maintain a
call frame and do a regular call. The regression is only a couple nanoseconds,
which seems well-explained by these differences explain, and ultimately is not a
big deal.
However, this does lead to a ~5% code size regression for compiled modules.
Before, we compiled a trampoline per escaping function's signature and we
deduplicated these trampolines by signature. Now we compile two trampolines per
escaping function: one for if the host calls via the array calling convention
and one for it the host calls via the native calling convention. Additionally,
we compile a trampoline for every type in the module, in case there is a native
calling convention function from the host that we `call_indirect` of that
type. Much of this is in the `.eh_frame` section in the compiled module, because
each of our trampolines needs an entry there. Note that the `.eh_frame` section
is not required for Wasmtime's correctness, and you can disable its generation
to shrink compiled module code size; we just emit it to play nice with external
unwinders and profilers. We believe there are code size gains available for
follow up work to offset this code size regression in the future.
Backing up a bit: the reason each Wasm module needs to provide these
Wasm-to-native trampolines is because `wasmtime::Func::wrap` and friends allow
embedders to create functions even when there is no compiler available, so they
cannot bring their own trampoline. Instead the Wasm module has to supply
it. This in turn means that we need to look up and patch in these Wasm-to-native
trampolines during roughly instantiation time. But instantiation is super hot,
and we don't want to add more passes over imports or any extra work on this
path. So we integrate with `wasmtime::InstancePre` to patch these trampolines in
ahead of time.

`proc_macro` crate, or as a fallback implementation of the crate, depending on
where it is used.
If using this crate on older versions of rustc (1.56 and earlier), it will
temporarily replace the panic handler while initializing in order to detect if
it is running within a `proc_macro`, which could lead to surprising behaviour.
This should not be an issue for more recent compiler versions, which support
`proc_macro::is_available()`.
The `proc-macro2` crate's fallback behaviour is not identical to the complex
behaviour of the rustc compiler (e.g. it does not perform unicode normalization
for identifiers), however it behaves well enough for its intended use-case
(tests and scripts processing rust code).
`proc-macro2` does not use unsafe code, however exposes one `unsafe` API to
allow bypassing checks in the fallback implementation when constructing
`Literal` using `from_str_unchecked`. This was intended to only be used by the
`quote!` macro, however it has been removed
(https://github.com/dtolnay/quote/commit/f621fe64a8a501cae8e95ebd6848e637bbc79078),
and is likely completely unused. Even when used, this API shouldn't be able to
cause unsoundness.

`quote` is a utility crate used by proc-macros to generate TokenStreams

This crate contains no unsafe code, and the internal logic, while difficult to

wasi-http supply chain audit (#6121)
* add cargo-deny exception for duplicate versions of windows-sys
* cargo vetting for all new deps introduced by https://github.com/bytecodealliance/wasmtime/pull/5929
The audits are straightforward. The exemptions, as always, need to be justified:
* core-foundation, core-foundation-sys, security-framework, security-framework-sys: these are large crates which are FFI bindings to Mac OS frameworks. As such they contain tons of unsafe code to make these FFI calls and manage memory. These crates are too big to audit.
* schannel: same as the above, except this is a windows component, which I'm also unfamiliar with.
* openssl, openssl-sys: also large FFI bindings which are impractical to audit.
* futures-macro, futures-task: while not as complex as futures-util, these are beyond my personal understanding of futures to vet practically. I've asked Alex to look at auditing these, and he will after he returns from vacation next week.
* futures-util: 25kloc of code, over 149 instances of the substring "unsafe" (case insensitive), this is impractical to audit in the extreme.
* h2, http, httparse, hyper, mio, tokio: this so-called tokio/hyper family are very large and challenging to audit. Bobby Holley has indicated that he is working to get the AWS engineers who maintain these crates to publish their own audits, which we can then import. We expect to exempt these until those imports are available.
