[clang][AArch64] Move initialization of ptrauth-* function attrs (#140277)
Move the initialization of ptrauth-* function attributes near the initialization of branch protection attributes. The semantics of these groups of attributes partially overlaps, so handle both groups in getDefaultFunctionAttributes() and setTargetAttributes() functions to prevent getting them out of sync. This fixes C++ TLS wrappers.
