Fix: Check if method implements any interface method from the codeunit's interface or interfaces it extends

Fix: Check if method implements any interface method from the codeunit's interface or interfaces it extends.
The method did not account for ISomeInterface extends ISomeBaseInterface, because that wasn't available with older runtimes.

This fixes false positives from LC0052 and LC0053 which check for unused internal procedures.

Hi @rvanbekkum , thank you for providing this fix for the false positieve.

Would it be possible to include automated test(s) in the PR for these scenarios?

[rvanbekkum]

False positive from LC0052 would be raised with this example:

interface IBase
{
    procedure SomeBaseInterfaceProcedure();
}

interface IExtended extends IBase
{
    procedure SomeExtendedInterfaceProcedure();
}

codeunit 51010 ExtendedImpl implements IExtended
{
    Access = Internal;

    procedure SomeBaseInterfaceProcedure()
    begin
        Message('Hello Base');
    end;

    procedure SomeExtendedInterfaceProcedure() // This would raise a false positive from LC0052, but this has been fixed.
    begin
        Message('Hello Extended');
    end;
}

would something of that form be a good test to ensure this false positive does not occur?
