### Default Precompiles

Default precompiles have been moved to `/evm/precompiles/types/defaults.go` and the function name was
changed to `DefaultStaticPrecompiles`. The function signature has also changed, and now takes pointers
as inputs for the `Erc20Keeper` and `TransferKeeper`. Finally, the `WithStaticPrecompiles` builder
function can now happen *alongside the keeper instantiation*, and not after. The new wiring is shown below:

```go
app.EVMKeeper = evmkeeper.NewKeeper(
appCodec, keys[evmtypes.StoreKey], tkeys[evmtypes.TransientKey], keys,
authtypes.NewModuleAddress(govtypes.ModuleName),
app.AccountKeeper,
app.PreciseBankKeeper,
app.StakingKeeper,
app.FeeMarketKeeper,
&app.ConsensusParamsKeeper,
&app.Erc20Keeper,
tracer,
).WithStaticPrecompiles(
precompiletypes.DefaultStaticPrecompiles(
*app.StakingKeeper,
app.DistrKeeper,
app.BankKeeper,
&app.Erc20Keeper, // UPDATED
&app.TransferKeeper, // UPDATED
app.IBCKeeper.ChannelKeeper,
app.GovKeeper,
app.SlashingKeeper,
appCodec,
),
)
```

It changed from the PreciseBankKeeper to normal BankKeeper here, is that intentional?
