Arm: Fix incorrect tailcall-generation for indirect calls [PR113780]

This patch fixes a bug that causes indirect calls in PAC-enabled functions
to be tailcalled incorrectly when all argument registers R0-R3 are used.

PR target/113780
* config/arm/arm.cc (arm_function_ok_for_sibcall): Don't allow

functions.

__ARM_FEATURE_PAUTH.
