Subject: [PATCH] perf: cs-etm: Update to build with latest opencsd version.

OpenCSD version v0.14.0 adds in a new output element. This is represented
by a new value in the generic element type enum, which must be added to
the handling code in perf cs-etm-decoder to prevent build errors due to
build options on the perf project.

This element is not currently used by the perf decoder.

Tested on Linux 5.7-rc1.
