Add `eip712HashType`, `eip712HashStruct`, and `eip712HashTypedData`
cheatcodes to VmSafe interface

```solidity
function eip712HashType(string calldata typeNameOrDefinition) external pure returns (bytes32 typeHash);
function eip712HashType(string calldata bindingsPath, string calldata typeName) external pure returns (bytes32 typeHash);
function eip712HashStruct(string calldata typeNameOrDefinition, bytes calldata abiEncodedData) external pure returns (bytes32 typeHash);
function eip712HashStruct(string calldata bindingsPath, string calldata typeName, bytes calldata abiEncodedData) external pure returns (bytes32 typeHash);
function eip712HashTypedData(string calldata jsonData) external pure returns (bytes32 digest);
```

Closes #690.

Avoid calling vm when the condition is trivial to check inline. This is
a minor performance improvement as a couple of opcodes execute a lot
faster than a full cheatcode pipeline (external call, EVM call
bookkeeping, abi encoding/decoding, ...) that eventually does nothing.

For example, [Uniswap's v4-core](https://github.com/Uniswap/v4-core/)
spends ~28% of the entire `forge test` CPU time in a couple of trivial
`assert` functions (uint256, bytes32, true, false), ~13% for `forge
coverage`. This is without accounting for the actual CALL/abi coding
etc.

These numbers are skewed due to profiling overhead, however making this
change does have ~5% overall test performance improvement, for no
compilation time change.

Optimize it ourselves.

Fixes #583.
