Add regexp support for $domain modifier

now there is no chance to create single cosmetic rule for hiding the same element on such domains: example1.com, example2.com, example3.org

it would be nice if $domain modifier supports regular expressions, just like $path does

something like this: [$domain=/example[0-9]\.(com|org)/]##.ad

Why limit just to the cosmetic rules? If we do it here, we should extend it to basic rules as well.

But let's wait until the CL guys come up with a proper syntax spec. https://github.com/AdguardTeam/CoreLibs/issues/1550
