Add Arm HWCAP2_* constants from Linux 3.15 and 6.2 to <bits/hwcap.h>
Linux 3.15 and 6.2 added HWCAP2_* values for Arm. These bits have
already been added to dl-procinfo.{c,h} in commits 9aea0cb842f02 and
8ebe9c0b38a9. Also add them to <bits/hwcap.h> so that they can be used
in user code. For example, for checking bits in the value returned by
getauxval(AT_HWCAP2).
