  [clang][PAC] Fix PAC codegen for final class dynamic_cast optimization (#152227)

The codegen for the final class dynamic_cast optimization fails to
consider pointer authentication. This change resolves this be simply
disabling the optimization when pointer authentication enabled.

(cherry picked from commit 726847829553079a13b1b7104f2c2db9dcda9c1d)
