Implement utility method for zero-padding EVM addresses in the Address class

[Torres-ssf]

When converting an EVM address to a Fuel address, it's essential to pad zeros.

To simplify this process we need to add utility methods within the Address class that will automatically handle this zero-padding for us. This enhancement will reduce potential errors for all applications interacting with the EVM address.

So we do have a couple of functions already implemented that do something similar, however not matching this exact developer experience. Our Address.fromEvmAddress currently expects a wrapped and padded address (to match our EvmAddress type) to obtain an Address.

The use case detailed by @Torres-ssf is more appropriate, as an address would be returned from the EVM unwrapped and unpadded, requiring the user to do such to pass it to our function. I'll raise a PR to improve the dev ex of this function.
