Update MSRV to 1.81.0 (#9692)

* Update MSRV to 1.81.0

Coupled with today's release of Rust 1.83 this bumps our MSRV on
Wasmtime to 1.81. This also updates the nightly used for testing too.

prtest:full

* Propagate some necessary features through Winch

* Remove std feature from adapter configuration

Looks to be historical at this point and is no longer needed
