  [TableGen] Simplify generated code for validateOperandClass (#117889)

Implement the register operand handling in validateOperandClass with a
table lookup instead of a potentially huge switch.

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.
