  [clang][AMDGPU] Fix -ast-print crash on expanded predicate builtins (#199963)

ExpandAMDGPUPredicateBuiltIn synthesized an IntegerLiteral typed
_Bool/bool — a shape no other producer creates, and one that
StmtPrinter::VisitIntegerLiteral has no case for. -ast-print on the
resulting if-condition hit llvm_unreachable.

Emit the canonical boolean literal instead:

- C++, C23, OpenCL, HIP: CXXBoolLiteralExpr 'bool'
- pre-C23 C: IntegerLiteral 'int'

In the C case this matches what <stdbool.h>'s true/false macros expand
to.

Fixes #199563
