Statically register host WASM functions (#10394)

* Statically register host WASM functions

* Fix `substrate-test-client` compilation

* Move `ExtendedHostFunctions` to `sp-wasm-interface`

* Fix `sp-runtime-interface` tests' compilation

* Fix `sc-executor-wasmtime` tests' compilation

* Use `runtime_interface` macro in `test-runner`

* Fix `sc-executor` tests' compilation

* Reformatting/`rustfmt`

* Add an extra comment regarding the `H` generic arg in `create_runtime`

* Even more `rustfmt`

* Depend on `wasmtime` without default features in `sp-wasm-interface`

* Bump version of `sp-wasm-interface` to 4.0.1

* Bump `sp-wasm-interface` in `Cargo.lock` too

* Bump all of the `sp-wasm-interface` requirements to 4.0.1

Maybe this will appease cargo-unleash?

* Revert "Bump all of the `sp-wasm-interface` requirements to 4.0.1"

This reverts commit 0f7ccf8e0f371542861121b145ab87af6541ac30.

* Make `cargo-unleash` happy (maybe)

* Use `cargo-unleash` to bump the crates' versions

* Align to review comments
