* Init `RuntimeLogger` automatically for each runtime api call

This pr change the runtime api in such a way to always and automatically
enable the `RuntimeLogger`. This enables the user to use `log` or
`tracing` from inside the runtime to create log messages. As logging
introduces some extra code and especially increases the size of the wasm
blob. It is advised to disable all logging completely with
`sp-api/disable-logging` when doing the wasm builds for the on-chain
wasm runtime.

Besides these changes, the pr also brings most of the logging found in
frame to the same format "runtime::*".

* harden benchmark tests against internal panics

unfortunately, setting the profile here doesn't do anything; we'd
need to set it in every leaf package anyway. However, as this was
just making the default explicit anyway, I think it's safe enough
to remove entirely.

good enough for now.

* impl_benchmark_test_suite for ImOnline

For this crate also, the test suite fails identically with and without
this change, so we can say that this change is not the cause of the
tests' failure to compile.

* impl_benchmark_test_suite for lottery

	Elections,
	crate::tests::ExtBuilder::default().desired_members(13).desired_runners_up(7),
	crate::tests::Test,
	exec_name = build_and_execute,
);
```

and have it expand out properly. A selected fragment of the expansion:

```rust
        fn test_benchmarks() {
            crate::tests::ExtBuilder::default()
                .desired_members(13)

* Prevent contracts from allocating a too large buffer

* Fix possible integer overflow

* Do not evict a contract from within a call stack

We don't want to trigger contract eviction automatically when
a contract is called. This is because those changes can be
reverted due to how storage transactions are used at the moment.
More Information:
https://github.com/paritytech/substrate/issues/6439#issuecomment-648754324

It can be re-introduced once the linked issue is resolved. In the meantime
`claim_surcharge` must be called to evict a contract.

* Lazily delete storage in on_initialize instead of when removing the contract

* Add missing documentation of new error

* Make Module::claim_surcharge public

It being the only dispatchable that is private is an oversight.

* review: Add final newline

* review: Simplify assert statement

* Add test that checks that partial remove of a contract works

* Premote warning to error

* Added missing docs for seal_terminate

* Lazy deletion should only take AVERAGE_ON_INITIALIZE_RATIO of the block

* Added informational about the lazy deletion throughput

* Avoid lazy deletion in case the block is already full

* Prevent queue decoding in case of an already full block

* Add test that checks that on_initialize honors block limits

* Make host functions return TrapReason

This avoids the need to manually store any trap reasons
to the `Runtime` from the host function. This adds the following
benefits:

* It properly composes with the upcoming chain extensions
* Missing to set a trap value is now a compile error

* Add chain extension

The chain extension is a way for the contract author to add new
host functions for contracts to call.

* Add tests for chain extensions

* Fix regression in set_rent.wat fixture

Not all offsets where properly updated when changing the fixtures
for the new salt on instantiate.

* review: Remove superflous .into()

* Make it possible to calculate the storage as often as you want

So, until now each Substrate based blockchain has calculated the storage
root once, at the end of the block. Now there is Frontier that wants to
calculate some intermediate storage root. However this failed on block
import. The problem with that was the extrinsics root. When building the
block we stored `Default::default()` as extrinsics root, because yeah,
we don't know the extrinsics root before finishing the block. At the end
this extrinsics root was then calculated. But on block import we passed
the already known extrinsics root. This was no problem, as we removed
this value at the end of the block. However when you all the storage
root in between, that changes the storage root between block building
and block import.

This pr changes this behavior. It removes the `ExtrinsicsRoot` storage
entry and also doesn't pass it anymore to `System::initialize`. By doing
it, we remove the difference in the storage and fix the storage root mismatch.

* Fix bug with incorrectly calculating the extrinscs root

* Review feedback

This is no longer necessary with storage transactions.

* fix docs

* Update frame/merkle-mountain-range/src/lib.rs
