tlv: add new RecordT[T, V] utility type

Browse Source 
In this commit, we add a new type, `RecordT[T, V]` to reduce some of the
common boiler plate for TLV types. This type lets you take either a
primitive type, or an existing Record, and gain common methods used to
create tlv streams.

It also serves as extra type annotation as well, since wire structs can
use this to wrap any existing type and gain the relevant record methods.

This implementation ensures that the very definition of the field also
binds the TLV type value. It does this by using the generated code to
map a struct like TlvType1 to an actually Type like Type(1).
