[sui-framework] Remove "delegate" and replace with stake (#9059)

This does a large rename of "delegation/delegate" (etc) to the
equivalent "stake" name, e.g., `request_add_delegation` becomes
`request_add_stake`.

## Move

### Entry functions renamed (all within `sui_system.move`):
```
request_add_delegation ~> request_add_stake
request_add_delegation_mul_coin ~> request_add_stake_mul_coin
request_add_delegation_with_locked_coin ~> request_add_stake_with_locked_coin
request_add_delegation_with_mul_locked_coin ~> request_add_stake_with_mul_locked_coin
request_withdraw_delegation ~> request_withdraw_stake
```

### Move Object fields

```
StakingPool::pending_delegation ~> pending_stake
StakedSui::delegation_activation_epoch ~> stake_activation_epoch 
```

### Sui types

This renames a couple sui types since they no longer made sense to be
called what they were:

```
DelegatedStake ~> Stake
DelegationStatus ~> StakeStatus
```

This then performs the core set of renamings to make the system happy
with this. So there are still a number of functions in Rust and
Typescript that will contain their old delegation name.

Note that on the typescript side we keep DelegatedStake since (1) there
was already a type called Stake (which meant something else) and in the
context that I could see it being used it appeared as though
DelegatedStake really did mean "this is my stake that I have delegated
to this validator."

## Test Plan 

Make sure existing tests still pass.

+This changes almost all occurences of "delegate", "delegation" (and various capitalizations/forms) to their equivalent "stake"-based name. Function names, function argument names, RPC endpoints, Move functions, and object fields have been updated with this new naming convention.
