Add coderef checks to Test2::Tools::Compare

[FractalBoy]

It would be nice to have coderef checks that work similar to hash/array/object. e.g:

use Test2::V0;

my $coderef = sub { 
    return 1, 1 if wantarray;
    return 1;
};
is($coderef, code { call_list [1, 1]; call 1 }, 'coderef returns 1 in scalar context and 1, 1 in list context');

Today, you have to do something like this:

use Test2::V0;

my $coderef = sub { 
    return 1, 1 if wantarray;
    return 1;
};
is($coderef, meta {
    prop reftype => 'CODE';
    prop this => check_set(
        validator(sub { my $ret = [$_->()]; ($ret->[0] == 1 and $ret->[1] == 1) ? 1 : 0 }),
        validator(sub { $_->() == 1 ? 1 : 0 }),
    );
}, 'coderef returns 1 in scalar context and 1, 1 in list context');

If there's a simpler way to do this today, please let me know.
