[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.
