Remove `personal` namespace from geth

[holiman]

Rationale

We have long been wanting to remove account management from geth. This proposal is a step towards that, by removing the personal namespace from geth.

With the upcoming 1.11 release, I think this would be a good time to do it.

UX affected

I think the most blatant PITA for users would be in scenarios where geth is used to sign clique blocks. However, it's a one-time effort to switch to use clef instead. Docs here: https://geth.ethereum.org/docs/clef/cliquesigning

Methods affected

Methods which have other alternatives

• personal.listAccounts
