Oliver Tale-Yazdi e80c24733f Lift dependencies to the workspace (Part 1) (#2070 )

Changes (partial https://github.com/paritytech/polkadot-sdk/issues/994):
- Set log to `0.4.20` everywhere
- Lift `log` to the workspace

Starting with a simpler one after seeing
https://github.com/paritytech/polkadot-sdk/pull/2065 from @jsdw.
This sets the `default-features` to `false` in the root and then
overwrites that in each create to its original value. This is necessary
since otherwise the `default` features are additive and its impossible
to disable them in the crate again once they are enabled in the
workspace.

I am using a tool to do this, so its mostly a test to see that it works
as expected.

xcm-emulator

XCM-Emulator is a tool to emulate XCM program execution using pre-configured runtimes, including those used to run on live networks, such as Kusama, Polkadot, Asset Hubs, et cetera. This allows for testing cross-chain message passing and verifying outcomes, weights, and side-effects. It is faster than spinning up a zombienet and as all the chains are in one process debugging using Clion is easy.

Limitations

As the messages do not physically go through the same messaging infrastructure there is some code that is not being tested compared to using slower E2E tests. In future it may be possible to run these XCM emulated tests as E2E tests (without changes).

As well as the XCM message transport being mocked out, so too are areas around consensus, in particular things like disputes, staking and iamonline events can't be tested.

Alternatives

If you just wish to test execution of various XCM instructions against the XCM VM then the xcm-simulator (in the Polkadot repo) is the perfect tool for this.
