  [AArch64][PAC] Move emission of LR checks in tail calls to AsmPrinter

Move the emission of the checks performed on the authenticated LR value
during tail calls to AArch64AsmPrinter class, so that different checker
sequences can be reused by pseudo instructions expanded there.
This adds one more option to AuthCheckMethod enumeration, the generic
XPAC variant which is not restricted to checking the LR register.
