core: switch EVM tx context in ApplyMessage (#30809)

This change relocates the EVM tx context switching to the ApplyMessage function.
With this change, we can remove a lot of EVM.SetTxContext calls before
message execution.

### Tracing API changes

- This PR replaces the `GasPrice` field of the `VMContext` struct with
  `BaseFee`. Users may instead take the effective gas price from
  `tx.EffectiveGasTipValue(env.BaseFee)`.
