intel/compiler: Split hw_type tables

intel/compiler: Split hw_type tables

Previously we were sharing tables between generations that were nearly
identical (i.e., Gen8 3-src adds HF support) and used a small bit of
code to handle the differences. This is kind of a mess if you want to
reject 64-bit types on platforms that don't support 64-bit types, so
split the tables, allowing each generation's table to list exactly what
it supports.
