LOG: [clang] Replace PointerUnion::dyn_cast with llvm::dyn_cast (NFC) (#230381)

PointerUnion::dyn_cast has been soft-deprecated in favor of
llvm::dyn_cast and llvm::dyn_cast_if_present.  This patch replaces the
former with llvm::dyn_cast where the operand is guaranteed to be
nonnull.

Note that MaterializeTemporaryExpr::State is always initialized or
updated to a nonnull pointer.  It is only set in:

- MaterializeTemporaryExpr::MaterializeTemporaryExpr
- MaterializeTemporaryExpr::setExtendingDecl
- ASTStmtReader::VisitMaterializeTemporaryExpr
