The runtime api implementation contained invalid unsafe trait bounds. `Sync` was never correct there
and `Send` should have not been "force implemented".
* Runtime API versioning
Related to issue #11577
Add support for multiple versions of a Runtime API. The purpose is to
have one main version of the API, which is considered stable and
multiple unstable (aka staging) ones.
How it works
===========
Some methods of the API trait can be tagged with `#[api_version(N)]`
attribute where N is version number bigger than the main one. Let's call
them **staging methods** for brevity.
The implementor of the API decides which version to implement.
Example (from https://github.com/paritytech/substrate/issues/11577#issuecomment-1145347025):
```
decl_runtime_apis! {
#{api_version(10)]
trait Test {
fn something() -> Vec<u8>;
#[api_version(11)]
fn new_cool_function() -> u32;
}
}
```
```
impl_runtime_apis! {
#[api_version(11)]
impl Test for Runtime {
fn something() -> Vec<u8> { vec![1, 2, 3] }
fn new_cool_function() -> u32 {
10
}
}
}
```
Version safety checks (currently not implemented)
=================================================
By default in the API trait all staging methods has got default
implementation calling `unimplemented!()`. This is a problem because if
the developer wants to implement version 11 in the example above and
forgets to add `fn new_cool_function()` in `impl_runtime_apis!` the
runtime will crash when the function is executed.
Ideally a compilation error should be generated in such cases.
TODOs
=====
Things not working well at the moment:
[ ] Version safety check
[ ] Integration tests of `primitives/api` are messed up a bit. More
specifically `primitives/api/test/tests/decl_and_impl.rs`
[ ] Integration test covering the new functionality.
[ ] Some duplicated code

Ensure that the sp api macros don't use functions without providing the full path to the function.
This hygiene ensures that we don't actually try to call a method of an imported trait for example.

* Do not call `initialize_block` before any runtime api
Before this change we always called `initialize_block` before calling
into the runtime. There was already support with `skip_initialize` to skip
the initialization. Almost no runtime_api requires that
`initialize_block` is called before. Actually this only leads to higher
execution times most of the time, because all runtime modules are
initialized and this is especially expensive when the block contained a
runtime upgrade.
TLDR: Do not call `initialize_block` before calling a runtime api.

* Make `decl_runtime_apis!` fail on methods with default implementation

* Implements mocking of runtime apis
This pr adds support for easily mock runtime api implementations for
tests by using the `mock_impl_runtime_apis!` macro. The syntax is
similar to `impl_runtime_apis!`. The mocked implementation automatically
implements `ApiExt`, `ApiErrorExt` and `Core` as these are required by
the runtime api traits, but not required in tests or only a subset of them.
