[AArch64] Add ARMv8.3 combined pointer authentication load instructions
Add support for ARMv8.3 LDRAA and LDRAB combined pointer authentication and
load instructions.
These instructions authenticate the base register and load 8 byte from it plus
a scaled 10-bit offset with optional writeback to update the base register.
A new instruction class (ldst_imm10) and operand type (AARCH64_OPND_ADDR_SIMM10)
were introduced to handle the special addressing form.
