feat(pauth): add/modify helpers to support QARMA3
QARMA3 is a pointer authentication algorithm that generates
the PAC codes.
The is_armv8_3_pauth_present() helper was modified in order to
consider the presence of the QARMA3 algorithm (i.e.: when
ID_AA64ISAR2_EL1.{GPA3, APA3} fields are not 0.
In addition, helper is_feat_pacqarma3_present() was implemented to
explicitly detect the presence of QARMA3 algorithm.
