Add event to pure proxy deletion

[rockbmb]

Description

The PureCreated event, used in the pure_proxy extrinsic, is used to track the creation of pure proxies.
It now has the extrinsic_index of the pure_proxy call from the block in which it was executed, which is required to kill the pure proxies later.

The pallet_proxy::kill_pure extrinsic now emits an event.

@ggwpez since this modifies an already existing Event variant, will this require migrating anything?

[bkchr]

You can get the extrinsic index from the EventRecord::Phase already. You don't need to store it here extra.

@bkchr thanks for pointing that out; will roll back that change, but still keep the PureKilled event.

Regarding EventRecord::Phase, I would like to update https://support.polkadot.network/support/solutions/articles/65000182196 § "Removing a Pure Proxy".

Just to check: there's no better way to check these data through the PJS dashboard than to use system::events for the block in which proxy.pureProxy was processed, correct?

Regarding EventRecord::Phase, I would like to update https://support.polkadot.network/support/solutions/articles/65000182196 § "Removing a Pure Proxy".

In the tutorial they are also subscan. Generally this is quite horrible and should not use PJS. However, I'm not sure if there already exists a dedicated proxy UI (probably mainly around multisigs right now).

Did you mean that they shouldn't be using both Subscan and PJS for this task?
