target/arm: Fix output of PAuth Auth
...
The ARM pseudocode installs the error_code into the original
pointer, not the encrypted pointer. The difference applies
within the 7 bits of pac data; the result should be the sign
extension of bit 55.
Add a testcase to that effect.

target/arm: Implement pauth_computepac
...
This is the main crypto routine, an implementation of QARMA.
This matches, as much as possible, ARM pseudocode.

target/arm: Implement pauth_addpac
...
This is not really functional yet, because the crypto is not yet
implemented. This, however follows the AddPAC pseudo function.

Stripping out the authentication data does not require any crypto,
it merely requires the virtual address parameters.
