Add support for the memory_failure trace event in the rasdaemon and add improvements & support for the vendor specific errors in the util/ras-mc-ctl.in.

Changes: v1 -> v2 1. Fix the feedback by Mauro for the fix patch for the exception in the ras-mc-ctl.in. 2. Rebased and grouped the previous v1 rasdaemon patches posted.

New subject: [PATCH v2 4/8] rasdaemon: ras-mc-ctl: Fix for exception when an event is not enabled

When an event is not enabled in the build and thus the event's table is not present in the SQLite DB, then the DBI would detect exception and ras-mc-ctl exit without read and log remaining event's information. Following is the error log when the devlink_event is not enabled, "DBD::SQLite::db prepare failed: no such table: devlink_event at ./ras-mc-ctl line 1198. Can't call method "execute" on an undefined value at ./ras-mc-ctl line 1199"

Add an extra check, whether an event is enabled in the build, before try reading the tables.
