[contracts] make `debug_message` execution outcome invariant to node debug logging setting

[agryaznov]

Follow-up to https://github.com/paritytech/substrate/pull/12953

FIFO was not really a good approach to the debug buffer, as it's not very efficient in computational sense. This PR targets to improve it as follows:

• the function just silently drops the message if no space left in the debug buffer, or when the message is not a valid utf-8 string;
• basically we make it indistinguishable from contract side, whether the message got logged or not;
• the gas for the function call is to be charged per byte of the passed message; updated benchmarks;

looks like we're waiting for new weights from here: https://github.com/paritytech/substrate/pull/13316

The extra commit I've just pushed is a workaround for this issue: https://github.com/paritytech/substrate/issues/13376

It replaces the dependency on wasmtime with our own fork with the fix applied (which is trivial). This is only temporary until (hopefully) it's fixed upstream in wasmtime. (But it should be fine to merge it as-is, assuming the CI will be happy with it.)
