* contracts-bedrock: update weth98

The custom gas token project is moving away from using
the original weth9 code as a predeploy to using the
weth98 code as a predeploy. As part of this, the ability
to override the name and symbol are required for chains
that use a custom gas token. There is no way to
mark an inline declaration as `virtual`, it requires
moving to a `function` syntax. Definitely less clean
looking but necessary to support the override ability.

The implementation of the new WETH predeploy is as follows:

```solidity
contract WETH is WETH98 {
    /// @notice Returns the name of the token from the L1Block contract
    function name() external view override returns (string memory) {
        return string.concat("Wrapped ", L1Block(Predeploys.L1_BLOCK_ATTRIBUTES).gasPayingTokenName());
    }

    /// @notice Returns the symbol of the token from the L1Block contract
    function symbol() external view override returns (string memory) {
        return string.concat("W", L1Block(Predeploys.L1_BLOCK_ATTRIBUTES).gasPayingTokenSymbol());
    }
}
```

Where when not in custom gas token mode, it with return `Wrapped Ether`
and `WETH`, so it is backwards compatible.

This commit also adds a fallback function since the original weth9 has
a fallback function but this one does not. While the receive function
can work, adding the fallback function ensures that the same behavior
as weth9 is achieved when making a call that includes calldata + value.
