WASM/PVM: add `store_create` for V1

Context

Fixes #5337 (closed)

Note that the function does not write any value, only allocates it. Zero-filled chunks are created on the fly when they're first accessed, hence the value can be created with size up to 2GB (the maximum addressable size in the durable storage, for 32bits).

Note that two commits are introduced to refactor a bit the testing of host functions that are tied to the PVM version (which explains why this MR depends on !8307 (merged)).

Manually testing the MR

dune exec src/lib_scoru_wasm/test/test_scoru_wasm.exe -- test "^Durable|^WASM PVM"
