Merge #14075: Import watch only pubkeys to the keypool if private keys are disabled

Browse source 
f4b00b70e Import public keys in order (Andrew Chow)
9e1551b9c Test pubkey import to keypool (Andrew Chow)
513719c5f Add option to importmulti add an imported pubkey to the keypool (Andrew Chow)
9b81fd19a Fetch keys from keypool when private keys are disabled (Andrew Chow)
99cccb900 Add a method to add a pubkey to the keypool (Andrew Chow)

Pull request description:

  If the wallet has private keys disabled, allow importing public keys into the keypool. A `keypool` option has been added to `importmulti` in order to signal that the keys should be added to the keypool.

Tree-SHA512: e88ea7bf726c13031aa739389a0c2662e6b22a4f9a4dc45b042418c692a950d98f170e0db80eb59e9c9063cda8765eaa85b2927d1790b9625744f7a87bad5fc8
