Codechange: Speed up industry generation using industry-type checks. (#13094)

Browse Source 
Store a list of industries per industry type. This allows industry generation checks which only consider a specific industry type to check a reduced set of industries, leading to a potential performance increase.

This also removes the need to track industry type counts as well.
