Fix tests and lints for new version of Rust

[jeffcharles]

Description of the change

The update to Rust 1.83 seems to have resulted in some parts of CI failing. This makes a few changes to get it passing:

• Elide some lifetimes
• Adjust target fuel slightly lower
• Add #![allow(static_mut_refs)] to a couple modules

Why am I making this change?

We need CI to pass. For the #![allow(static_mut_refs)], I looked into some alternatives but wasn't able to find a satisfying alternative. In the plugin, using another approach is going to introduce some overhead. In the codegen, I tried moving setting up the WASI context into the closure used to add WASI p1 to the linker in make_linker but that causes building modules to hang and apparently that's not unexpected (see bytecodealliance/wasmtime#9723). I also tried using an "immutable" static RefCell but the Rust compiler complains that WasiCtx doesn't implement 'sync. And trying to put a mutex around the RefCell or using an RwLock doesn't work because the closure needs to return a mutable reference but has to drop the lock when it returns which invalidates the reference. Arc's also aren't supported as a top-level type for statics.
