    Add Arm HWCAP values from Linux 6.2 to bits/hwcap.h
    
    Linux 6.2 adds six new Arm HWCAP values and two new HWCAP2 values; add
    them to glibc's Arm bits/hwcap.h, with corresponding dl-procinfo.c and
    dl-procinfo.h updates.
    
    Tested with build-many-glibcs.py for arm-linux-gnueabi.
