[CIR] Upstream initial support for switch statements (#137106) This introduces initial support for the switchOP, with caseOP of the Equal kind. Support for additional case kinds such as AnyOf, Range, and Default will be included in a future patch. Similarly, lowering to LLVM IR and flattening of the switch are deferred and will be addressed in subsequent updates.
