Subject: kasan: rename report and tags files

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.
