Remove `expect(clippy::allow_attributes_without_reason)` from cranelift-codegen (#11182)
* Remove `expect(clippy::allow_attributes_without_reason)` from cranelift-codegen
This commit gets around to migrating the `cranelift-codegen` crate to
require a reason on lint directives and additionally switch to
`#[expect]` where possible.

Cranelift: Add a new backend for emitting Pulley bytecode (#9089)
* Cranelift: Add a new backend for emitting Pulley bytecode
This commit adds two new backends for Cranelift that emits 32- and 64-bit Pulley
bytecode. The backends are both actually the same, with a common implementation
living in `cranelift/codegen/src/isa/pulley_shared`. Each backend configures an
ISA flag that determines the pointer size, and lowering inspects this flag's
value when lowering memory accesses.
To avoid multiple ISLE compilation units, and to avoid compiling duplicate
copies of Pulley's generated `MInst`, I couldn't use `MInst` as the `MachInst`
implementation directly. Instead, there is an `InstAndKind` type that is a
newtype over the generated `MInst` but which also carries a phantom type
parameter that implements the `PulleyTargetKind` trait. There are two
implementations of this trait, a 32- and 64-bit version. This is necessary
because there are various static trait methods for the mach backend which we
must implement, and which return the pointer width, but don't have access to any
`self`. Therefore, we are forced to monomorphize some amount of code. This type
parameter is fairly infectious, and all the "big" backend
types (`PulleyBackend<P>`, `PulleyABICallSite<P>`, etc...) are parameterized
over it. Nonetheless, not everything is parameterized over a `PulleyTargetKind`,
and we manage to avoid duplicate `MInst` definitions and lowering code.
Note that many methods are still stubbed out with `todo!`s. It is expected that
we will fill in those implementations as the work on Pulley progresses.
* Trust the `pulley-interpreter` crate, as it is part of our workspace
* fix some clippy warnings
* Fix a dead-code warning from inside generated code
* Use a helper for emitting br_if+comparison instructions
* Add a helper for converting `Reg` to `pulley_interpreter::XReg`
* Add version to pulley workspace dependency
* search the pulley directory for crates in the publish script
