  1. catalog: improve how TableColMap handles system columns 

    Previously, `TableColMap` would very often incur an allocation when
mapping from system columns are set (because system columns have very
large IDs). This commit teaches `TableColMap` to handle the system
columns separately which allows us to remove those allocations.
