Powered by the previous commit this change updates the internal implementation details of wasmtime::Memory to avoid the need for the use of Stored. This means that converting from a Wasmtime-internal representation of a memory to an external representation of a memory is largely a noop and no longer requires an allocation. This is intended to be more useful in the future to use the public types more pervasively inside of Wasmtime itself, but for now this is mostly the scaffolding necessary for such a change.

This adds `#[inline]` to some functions which are otherwise not
available for cross-crate inlining. These functions started being more
heavily used after historical refactorings such as bytecodealliance#10877 so this helps
benchmarks which access linear memory in host functions, for example.
