kasan: add hardware tag-based mode for arm64 | expand

Commit Message

Andrey Konovalov Nov. 13, 2020, 10:15 p.m. UTC

Rename generic_report.c to report_generic.c and tags_report.c to
report_sw_tags.c, as their content is more relevant to report.c file.
Also rename tags.c to sw_tags.c to better reflect that this file contains
code for software tag-based mode.

No functional changes.
