* core/finality-grandpa: Rename VoteOrPrecommit to PrevoteOrPrecommit

According to the Grandpa paper [1]:

> A vote is a block hash, together with some metadata such as round
number and the type of vote, such as prevote or precommit, all signed
with a voter’s private key.

To reduce confusion this patch makes the code consistent with the
research paper.

* Add missing newline

* Split up DataProvider into CreateInherents and CheckInherents

* Make `wasmi_execution` public to use it from tests

* Make `WasmRuntime` accessible as well

* Add `call_in_wasm` instead of making stuff public

* Use `WasmRuntime`

* Move test

* More feedback

* split implementation in multiple files:
  * transformation -> genesis_config/  getters.rs  instance_trait.rs  metadata.rs  mod.rs  store_trait.rs
  * mod.rs -> parser.rs
  * impl.rs -> storage_struct.rs
* parser is isolated into parse module, it could be improved as well but this can be done in another PR
* modules contains a defintion of decl_storage input which must be ok to work with.
* implementation change:
  * T: Trait might be more often bound to 'static (anyway we only use static one and it is needed for metadata current implementation).
  * GenesisConfig no longer requires its fields to be Clone (possible since to EncodeLike feature)
  * builder for map storages must return precise type Vec<(key, value)>

The macro generates the functions with the signature we expect for wasm
functions. This macro is useful for tests where we need to call into
wasm. Parameter passing is done by SCALE encoding the input and output
parameters.

The `chain::error::FutureResult` doc is currently referring to the wrong
structure

This function executes the given closure in a context where the test

test externalities need to be created anyway.
