Speed up compilation of all our WriteAttribute machinery.

It turns out that instantiating fairly heavy-weight templates hundreds of times is slow to compile. Instead of having an instantiation per attribute, switch to only instantiating the complex templates per _type_ of attribute, with thin per-attribute wrappers for auto-deriving the cluster id and attribute id. This shaves over a minute of wall-clock time off compiling chip-tool for me, and close to 2 minutes of total CPU time.
