Introduce storage attr macro #[disable_try_decode_storage] and set it on System::Events and ParachainSystem::HostConfiguration (#3454)

Closes https://github.com/paritytech/polkadot-sdk/issues/2560

Allows marking storage items with `#[disable_try_decode_storage]`, and
uses it with `System::Events`.

Question: what's the recommended way to write a test for this? I
couldn't find a test for similar existing macro `#[whitelist_storage]`.

doc:
- audience: Runtime Dev
description: |
Allows marking storage items with \#[disable_try_decode_storage], which disables that storage item from being decoded
during try_decode_entire_state calls.
Applied the attribute to System::Events to close https://github.com/paritytech/polkadot-sdk/issues/2560.
Applied the attribute to ParachainSystem::HostConfiguration to resolve periodic issues with it.
