  [TableGen] Simplify generated code for isSubclass (#117351)

Implement isSubclass with direct lookup into some tables instead of
nested switches.

Part of the motivation for this is improving compile time when clang-18
is used as a host compiler, since it seems to have trouble with very
large switch statements.
