* Enhance `async` configuration of `bindgen!` macro (#6942)

This commit takes a leaf out of `wiggle`'s book to enable bindings
generation for async host functions where only some host functions are
async instead of all of them. This enhances the `async` key with a few
more options:

    async: {
        except_imports: ["foo"],
        only_imports: ["bar"],
    }

This is beyond what `wiggle` supports where either an allow-list or
deny-list can be specified (although only one can be specified). This
can be useful if either the list of sync imports or the list of async
imports is small.

* Partially revert CLI argument changes from #6737 (#6944)

* Partially revert CLI argument changes from #6737

This commit is a partial revert of #6737. That change was reverted
in #6830 for the 12.0.0 release of Wasmtime and otherwise it's currently
slated to get released with the 13.0.0 release of Wasmtime. Discussion
at today's Wasmtime meeting concluded that it's best to couple this
change with #6925 as a single release rather than spread out across
multiple releases. This commit is thus the revert of #6737, although
it's a partial revert in that I've kept many of the new tests added to
showcase the differences before/after when the change lands.

This means that Wasmtime 13.0.0 will exhibit the same CLI behavior as
12.0.0 and all prior releases. The 14.0.0 release will have both a new
CLI and new argument passing semantics. I'll revert this revert (aka
re-land #6737) once the 13.0.0 release branch is created and `main`
becomes 14.0.0.

* Update release notes

* riscv64: Use `PCRelLo12I` relocation on Loads (#6938)

* riscv64: Use `PCRelLo12I` relocation on Loads

* riscv64: Strenghten pattern matching when emitting Load's

* riscv64: Clarify some of the load address logic

* riscv64: Even stronger matching

* Update Rust in CI to 1.72.0, clarify Wasmtime's MSRV (#6900)

* Update Rust in CI to 1.72.0

* Update CI, tooling, and docs for MSRV

This commit codifies an MSRV policy for Wasmtime at "stable minus two"
meaning that the latest three releases of Rust will be supported. This
is enforced on CI with a full test suite job running on Linux x86_64
with the minimum supported Rust version. The full test suite will use
the latest stable version. A downside of this approach is that new
changes may break MSRV support on non-Linux or non-x86_64 platforms and
we won't know about it, but that's deemed a minor enough risk at this
time.

A minor fix is applied to Wasmtime's `Cargo.toml` to support Rust 1.70.0
instead of requiring Rust 1.71.0

* Fix installation of rust

* Scrape MSRV from Cargo.toml

* Cranelift is the same as Wasmtime's MSRV now, more words too

* Fix a typo

* aarch64: Use `RegScaled*` addressing modes (#6945)

This commit adds a few cases to `amode` construction on AArch64 for
using the `RegScaled*` variants of `AMode`. This won't affect wasm due
to this only matching the sign-extension happening before the shift, but
it should otherwise help non-wasm Cranelift use cases.

Closes #6742

* cranelift: Validate `iconst` ranges (#6850)

* cranelift: Validate `iconst` ranges

Add the following checks:

`iconst.i8`  immediate must be within 0 .. 2^8-1
`iconst.i16` immediate must be within 0 .. 2^16-1
`iconst.i32` immediate must be within 0 .. 2^32-1

Resolves #3059

* cranelift: Parse `iconst` according to its type

Modifies the parser for textual CLIF so that V in `iconst.T V` is
parsed according to T.

Before this commit, something like `iconst.i32 0xffff_ffff_ffff` was
valid because all `iconst` were parsed the same as an
`iconst.i64`. Now the above example will throw an error.

Also, a negative immediate as in `iconst.iN -X` is now converted to
`2^N - X`.

This commit also fixes some broken tests.

* cranelift: Update tests to match new CLIF parser

* Some minor fixes and features for WASI and sockets (#6948)

* Use `command::add_to_linker` in tests to reduce the number of times
  all the `add_to_linker` are listed.
* Add all `wasi:sockets` interfaces currently implemented to both the
  sync and async `command` functions (this enables all the interfaces in
  the CLI for example).
* Use `tokio::net::TcpStream::try_io` whenever I/O is performed on a
  socket, ensuring that readable/writable flags are set/cleared
  appropriately (otherwise once readable a socket is infinitely readable).
* Add a `with_ambient_tokio_runtime` helper function to use when
  creating a `tokio::net::TcpStream` since otherwise it panics due to a
  lack of active runtime in a synchronous context.
* Add `WouldBlock` handling to return a 0-length read.
* Add an `--inherit-network` CLI flag to enable basic usage of sockets
  in the CLI.

This will conflict a small amount with #6877 but should be easy to
resolve, and otherwise this targets different usability points/issues
than that PR.
