SCORU: Wasm PVM: implement store_has
Goal
Implement the store_has
host capability (see docs).
This allows a kernel to retrieve whether a given key exists in the durable storage.
The host function should be compatible with:
(module
...
(type (;2;) (func (param i32 i32) (result i32)))
...
(import "rollup_safe_core" "store_has" (func (;2;) (type 2)))
...
