Indexed fields cookie changes

[jgoday]

This PR tries to implement a fields indexed cookie view to avoid allocation memory whenever possible. It was suggested by @tusharmath in a previous PR (#576).

• It defines a Cookie trait with the basic properties and method signatures.
• CookieImpl as a case class to instantiate a cookie with all of his fields when necessary. Cookie object apply method invokes this case class.
• A CookieView that takes a raw string cookie value. It postpones memory allocation (of each field) until needed.
• CookieBuilder trait to allow mutate a cookie.

I'm not really sure about naming anyway, CookieImpl does not convince me at all.

This are the CookieDecodeBenchmark results (it's not very fair to compare them ...).

Hi @tusharmath, what do you think about this implementation ?

[tusharmath]

Cookie rewrite #1414 internally uses netty's decoder/encoder. I don't think ZIO Http needs to worry about it anymore.

Thanks @jgoday ! Closing this now.
