[NFC][AArch64][ELF][PAC] Update AUTH relocation IDs (#74986)

https://github.com/ARM-software/abi-aa/pull/227 changes IDs of
`R_AARCH64_AUTH_ABS64` and `R_AARCH64_AUTH_RELATIVE` in PAuth ABI
specification from draft ones (`0xe100` and `0xe200`) to final ones
(`0x244` and `0x411`).

This patch changes the values in llvm correspondingly.
