(BIDS-2782) Remove duplicated code in two functions of eth1Account.go

[thib-wien]

Removes identical code appearing in functions Eth1Address() and Eth1AddressWithdrawals() in eth1Account.go.
Instead, this duplicated logic is moved into GetAddressWithdrawals() in db.go.

I recommend the reviewer to study the modifications in Eth1Address() and Eth1AddressWithdrawals() before studying GetAddressWithdrawals(), it will help understanding.

Refactored and simplified the code for fetching and displaying eth1 address withdrawals. Used the html/template package and a common response type for the withdrawals table. Improved the handling of no withdrawals and currency conversion.

Please have a look at my comments.

The new withdrawals function should be kept as similar to the other address page tabs functions as possible.
E.g. the tmr warning they have at the start can also be added.

On Prater I used this address for testing purposes since it has enough withdrawals to require a few scroll loads to show all of them but not too many so that you can actually reach the end in a few loads.

When I use this one with your changes I get a "Something went wrong fetching please try again another time." at the end.
I did not test this on current master.

@Eisei24
The bug seems to be fixed :)
I also did the little improvements that you suggested.

You can still delete the setting of Draw and RecordsTotal in the emptyData if you want.
